NuGen Rewind SNP Curation v2 — Validation Report

Scope: All 34 SNPs across RW-T01 through RW-T05. Each entry checked against dbSNP/ClinVar records, primary literature, and meta-analyses. Issues are graded: 🔴 Error (fix required), 🟡 Caveat (annotate or flag), 🟢 Confirmed.

RW-T01 — Genomic Instability Tendency

rsID	Finding	Status
rs1801270 CDKN1A Ser31Arg C>A	Confirmed: A allele encodes Arg31; reduces p21 accumulation under DNA damage; published association with reduced G1/S checkpoint fidelity. Mechanism text is accurate.	🟢
rs1042522 TP53 Pro72Arg G>C	Confirmed: G = Arg72, C = Pro72. The mechanism description — Arg72 favours faster apoptosis over cell-cycle arrest — is the consensus view. Note: the direction is debated across cancer types and ethnic groups (Arg72 is risk for some cancers but protective in others). This variant has strong SA-specific data; the document correctly gives it highest SA priority.	🟢 / 🟡 Direction caveat should be `ancestry_or_exposure`
rs1799977 MLH1 c.655A>G p.Ile219Val	Confirmed: G = Val219. ClinVar classifies this as Likely Benign / Benign for Lynch syndrome. The "subtle MMR efficiency variation" framing is appropriate for a wellness (non-diagnostic) context. T3 tier appropriate.	🟢
rs2228001 XPC Lys939Gln A>C	Confirmed: C = Gln939. The A>C assignment is correct (exon 15). Meta-analyses confirm modestly increased cancer risk (OR ~1.07 per allele overall; stronger in Asian populations for bladder/lung/digestive). Mechanism text accurate.	🟢
rs2228000 XPC Ala499Val C>T	Confirmed: T = Val499. Strong LD with rs2228001. The document's caveat ("conflicting cancer-risk direction by tissue") is validated — meta-analyses show elevated risk in some cancer types but protective effects in others. T3 + open-item #3 are appropriate.	🟢
rs13181 ERCC2/XPD Lys751Gln	🔴 Allele notation inconsistency. The document states A>C with C = Gln751. However, multiple published papers (PMC11984361, PMC5564835, PMC4613026) consistently report rs13181 as a T>G substitution at codon 751, where G = Gln751 is the risk allele. The A>C notation appears to be a transversion notation variant that does not match the canonical dbSNP forward-strand representation. You should confirm strand orientation in your genotyping array and lock the notation. The risk direction (Gln = reduced NER efficiency) is correct regardless of notation.	🔴 Allele notation: confirm T>G (G = Gln) vs A>C (C = Gln) against your array manifest

RW-T01 count: 6 SNPs (rs4987117 correctly dropped). ✅

RW-T02 — DNA Repair Capacity (BER + NER)

rsID	Finding	Status
rs25487 XRCC1 Arg399Gln G>A	Confirmed: A = Gln399. BER scaffold role well established. Meta-analyses in Indian populations (PMID 19266243 and others) confirm this as highest-priority SA-flagged SNP.	🟢
rs1799782 XRCC1 Arg194Trp C>T	Confirmed: T = Trp194. Secondary BER scaffold allele; protein-protein interaction domain effect is published.	🟢
rs3213245 XRCC1 −77T>C promoter	🟡 Weak evidence flag. This is a valid XRCC1 promoter SNP and the expression-reduction mechanism is described in the literature. However, it has far fewer replication studies than rs25487 or rs1799782. The T2 tier and the v2 note (nomenclature added) are reasonable. No factual error, but confidence is lower than T2 implies for some populations.	🟡 Consider downgrade to T3 pending SA replication data
rs1052133 OGG1 Ser326Cys C>G	Confirmed: G = Cys326. ~30–50% reduction in enzymatic activity for 8-oxoguanine excision is the consensus figure from multiple studies. T1 appropriate.	🟢
rs1760944 APEX1	🔴 Ongoing ambiguity not fully resolved. The document correctly flags the conflation with rs3136820 (Asp148Glu coding variant). However, the risk allele annotation is internally inconsistent: it states "T allele = risk in Asian PCa MA" but then says "G/M allele associated with lower cancer risk," implying G (not T) is protective — which means T is risk. That internal logic is consistent but the "T>G" direction and the "M allele −141T>G in APE1 promoter" reference do not match standard dbSNP records for rs1760944, which is an intronic variant in APEX1 without a well-established promoter annotation. The action item (confirm with curator which variant is intended) remains mandatory before encoding.	🔴 Do not encode until curator confirms rs1760944 vs rs3136820
rs238406 ERCC1 C>A codon 118/8092	🟡 Variant annotation needs precision. rs238406 maps to the 3'UTR region of ERCC1 (the "8092" region) rather than codon 118 coding change. The codon 118 synonymous change is a separate variant (rs11615). These two ERCC1 SNPs are often reported together in the literature, but they are distinct positions. The mechanism listed (reduces ERCC1 mRNA stability) aligns with the 3'UTR/8092 rs238406 annotation, so the rsID is probably correct — but the "codon 118" label is misleading and should be removed.	🟡 Remove "codon 118" from variant description; label as "3'UTR/8092 region"
rs13181 ERCC2/XPD	Same notation caveat as RW-T01 applies here. Cross-listing is appropriate.	🔴 (same notation issue)

RW-T02 count: 7 SNPs. ✅

RW-T03 — Double-Strand Break Repair (HR + NHEJ)

rsID	Finding	Status
rs1801320 RAD51 5'UTR G>C position 135	Confirmed: C allele reduces RAD51 mRNA stability → impaired HR. T1 appropriate. The CC genotype annotation for "lowest DRC" is supported in the literature.	🟢
rs1801321 RAD51 5'UTR G>T position 172	Confirmed: in high LD with rs1801320. Demotion to haplotype tag with "do not include in per-allele sum" is the correct handling per current literature — the two RAD51 5'UTR variants are frequently co-inherited and scoring both would double-count the same signal.	🟢
rs861539 XRCC3 Thr241Met C>T	Confirmed: T = Met241. XRCC3 assists RAD51 in HR strand-invasion complex; Met allele reduces HR efficiency — well supported.	🟢
rs3218536 XRCC2 Arg188His G>A	Confirmed: v2 correction from rs2278307 → rs3218536 is correct. XRCC2 Arg188His is definitively rs3218536 (PMID 24621646, as cited in the document).	🟢
rs1805794 NBN Glu185Gln G>C	Confirmed: v2 correction from rs1800932 → rs1805794 is correct. NBN (Nibrin) Glu185Gln = rs1805794; MRN complex DSB sensing role is accurate.	🟢
rs2075685 XRCC4 Promoter	🟡 Thin evidence. XRCC4 promoter variants have been studied but rs2075685 has limited replication, particularly in non-European cohorts. The T3 tier is appropriate. The "T = lower expression allele" claim should be flagged for SA validation before scoring.	🟡 T3 appropriate; flag for SA validation
rs1805388 LIG4 Thr9Ile C>T	🟡 Modest evidence base. LIG4 Thr9Ile is a real variant with plausible NHEJ ligation kinetic effects, but the published literature on its functional impact is thin compared to T1/T2 markers. T3 is appropriate.	🟡 T3 appropriate

RW-T03 count: 7 SNPs (rs1801321 correctly retained as haplotype tag, not counted in per-allele sum). ✅

RW-T04 — Telomere Maintenance Tendency

rsID	Finding	Status
rs2736100 TERT A>C intron 4	🔴 Risk direction requires caveat elevation. The document states A = shorter telomere in peripheral blood (risk), and this is correct for non-cancerous disease (IPF, cardiovascular). However, the C allele is robustly associated with increased cancer risk (lung, glioma, bladder, testicular) because it is linked to longer telomeres and upregulated TERT expression — which is pro-oncogenic. The document acknowledges a tissue caveat (C3 in changelog) but the body text only describes A as "risk" without explicitly stating that C is the cancer risk allele. For a longevity/rewind context, the directional encoding is ambiguous: shorter telomeres → accelerated aging, but longer telomeres → cancer predisposition. This must be encoded as `direction_caveat: tissue_specific` and the scoring role must specify which phenotype axis is being scored.	🔴 Clarify which phenotype axis (telomere-length aging vs cancer risk) drives the per-allele contribution; C allele = cancer risk allele must be explicitly flagged
rs12696304 TERC C>G	Confirmed: C = shorter telomere in multiple large GWAS (Codd 2013, others). Strongest global telomere-length signal. T1 appropriate.	🟢
rs2297439 RTEL1 SA-specific signal	Confirmed as SA-specific signal from Delgado 2018. T2 (SA-GWAS) tier is appropriate. Note: the variant annotation says "Intron, novel SA signal" without specifying the exact allele change — this should be populated from the Delgado 2018 paper's supplementary tables before encoding.	🟡 Populate exact allele change from Delgado 2018
rs8105767 ZNF208 19p13.2	🟡 Moderate evidence. ZNF208 has appeared in telomere-length GWAS but with inconsistent replication across populations. The mechanism (HERV-K retrotransposon regulation affecting telomere maintenance) is plausible but indirect. T2 may be slightly generous; T3 more defensible for non-EUR populations.	🟡 Consider T3 for SA scoring weight
rs10936599 TERC region/MYNN 3q26	Confirmed in Codd 2013 GWAS. T allele → shorter telomere direction is correct. T2 appropriate.	🟢
rs755017 RTEL1 20q13.33 EUR signal	Confirmed in Codd 2013. A = shorter telomere. The PRS transferability note correctly flags that this EUR signal may not replicate in SA populations — appropriate T2 with SA caveat.	🟢
rs9420907 OBFC1/STN1 10q24.33	Confirmed: CST complex role in lagging-strand telomere synthesis is accurate. C = shorter telomere. T2 appropriate.	🟢

PRS transferability note: The Delgado 2018 recommendation (SA-calibrated weights as primary, Codd 2013 EUR as fallback) is scientifically sound and should be implemented as stated. ✅

RW-T04 count: 7 SNPs. ✅

RW-T05 — Cellular Stress-Response Resilience

rsID	Finding	Status
rs1043618 HSPA1A −110A>C	Confirmed: promoter variant reducing inducible HSP70-1 expression. C allele → lower stress-induced HSP70. T3 appropriate given modest and ethnically variable evidence base.	🟢
rs1061581 HSPA1B A1267G	Confirmed: v2 correction from rs539689 → rs1061581 is correct. rs1061581 (A1267G) is the HSPA1B variant described in the Danish 1905 cohort survival study. The G-C-T haplotype longevity association is real. T3 appropriate.	🟢
rs2227956 HSPA1L T2437C	🟡 Mechanism text imprecision. The document says C allele → "higher TNF-α stress signal." The published data link HSPA1L variants to cytokine co-production, but direct causal evidence for rs2227956 specifically driving TNF-α elevation is limited. The label "constitutive cytosolic HSP70" is also slightly off — HSPA1L (HSP70-hom) is a constitutive form but it functions more in the nucleus and antigen presentation context than as a general cytosolic chaperone. T3 is appropriate; the mechanism text should be softened to "associated with altered inflammatory cytokine balance."	🟡 Soften mechanism text
rs2908004 HSF1 Promoter/intron	🟡 rsID poorly characterized. HSF1 SNPs have been studied in stress-response and longevity contexts, but rs2908004 has limited published characterization as a standalone functional variant. The "minor allele → blunted heat-shock response across all HSPs" mechanism is plausible via reduced HSF1 transcription, but this specific rsID's function is not well replicated. T3 appropriate; tag as `evidence_tier: T3` with `reduced_transferability`.	🟡 Flag for curator confirmation of rsID functional evidence
rs6721961 NFE2L2/NRF2 −617C>A	Confirmed: v2 correction from rs8192288 → rs6721961 is correct. rs6721961 is the canonical NFE2L2 promoter SNP studied in oxidative stress contexts. A allele → reduced NRF2 transcription → lower glutathione/thioredoxin induction. T2 appropriate.	🟢
rs2802292 FOXO3A Intron 2 G>T	Confirmed: v2 correction from rs25651 → rs2802292 is correct. This is the canonical FOXO3A longevity SNP with meta-analytic support across multiple populations (PMID 24589462, 27621247). G = longevity-protective. Mechanism (insulin/IGF-1 + oxidative stress → longevity) is accurate. A 2018 paper (PMID 29733381) clarifies the intronic enhancer mechanism: rs2802292 sits in an HSF1-responsive enhancer driving FOXO3 expression under stress — which is directly relevant to RW-T05's hormetic context. T1 appropriate.	🟢
rs391957 HSPA5 T>C	Confirmed: Indian longevity study (PMID 39567526) reports T allele enriched in LLIs (OR ~1.59, 95% CI 1.22–2.06). The document's mechanism text correctly states ER-resident chaperone/UPR master regulator. However, the primary mechanism of the longevity association appears to be anxiety/neuroticism reduction (the paper explicitly states this), not UPR proteostasis per se. The document frames it as proteostasis — that is partially accurate (HSPA5 does regulate UPR) but omits the primary published mechanism for the longevity signal. Consider amending the mechanism text to include both.	🟡 Amend mechanism: add "T allele associated with reduced anxiety/neuroticism in published studies; longevity association in Indian LLI cohort (PMID 39567526) likely mediated through both UPR regulation and stress-resilience pathways"

RW-T05 count: 7 SNPs (including rs391957). ✅

Summary of Findings

🔴 Errors — Must Fix Before Encoding

#	Trait	Issue
E1	RW-T01, RW-T02	rs13181 ERCC2/XPD allele notation: Published literature consistently reports T>G (G = Gln751 risk), not A>C (C = Gln751). Confirm against array manifest and standardize notation.
E2	RW-T02	rs1760944 APEX1: Risk allele annotation is internally contradictory and the regulatory rsID vs coding rsID ambiguity is unresolved. Do not encode until curator confirms intended variant.
E3	RW-T04	rs2736100 TERT directionality: A = shorter telomere (aging axis) but C = cancer risk (oncogenic axis). The current encoding treats A as univocal "risk" which is incorrect for a cancer-inclusive longevity model. Must encode `direction_caveat: tissue_specific` and define the scoring phenotype axis explicitly.

🟡 Caveats — Annotate or Address Before Production

#	Trait	Issue
C1	RW-T01	rs1042522 TP53 Pro72Arg: add `direction_caveat: ancestry_or_exposure` — risk direction varies by cancer type and population
C2	RW-T02	rs3213245 XRCC1 −77T>C: consider downgrade to T3 pending SA replication
C3	RW-T02	rs238406 ERCC1: remove "codon 118" label; this is a 3'UTR/8092 region variant, not a coding change at codon 118
C4	RW-T04	rs2297439 RTEL1: populate exact allele change from Delgado 2018 supplementary before encoding
C5	RW-T04	rs8105767 ZNF208: evidence for non-EUR populations is thin; consider T3 weight in SA scoring
C6	RW-T05	rs2227956 HSPA1L: soften mechanism text; "higher TNF-α" causal claim is not directly established for this rsID
C7	RW-T05	rs2908004 HSF1: functional evidence for this specific rsID is limited; flag `reduced_transferability`
C8	RW-T05	rs391957 HSPA5: mechanism text should reflect that the Indian LLI longevity signal is primarily associated with anxiety/neuroticism reduction, not solely UPR proteostasis

RW-T06 — Epigenetic Maintenance Tendency

Pattern: per_allele_sum Rewind context: Genetic tendency toward stable DNA-methylation and chromatin patterning; shapes emphasis on biological-age-protective routines. Marker count: 6

rsID	Gene	Variant	Risk/unfavourable allele	Mechanism	Tier	Direction caveat	SA notes
rs2424913	DNMT3B	−149C>T (promoter)	T (higher DNMT3B expression)	De novo DNA methyltransferase; T allele drives promoter overactivity → hypermethylation of tumour-suppressor loci; associated with aberrant CpG island methylation in ageing tissues and cancer risk	T2	tissue_specific	T allele frequency SAS ~0.34; studied in Indian cancer cohorts (cervical, colorectal)
rs1569686	DNMT3A	Intron / regulatory	G (reduced DNMT3A)	De novo methyltransferase; G allele associated with reduced DNMT3A expression → global hypomethylation drift, particularly at repetitive elements; published in epigenetic-clock acceleration studies	T2	none	SAS frequency not yet well characterised; use EUR prior with 0.5× confidence discount until SA data available
rs2228611	DNMT1	Exon, synonymous/regulatory	A (reduced maintenance methylation fidelity)	Maintenance methyltransferase responsible for replicating methylation patterns post-division; A allele associated with reduced DNMT1 expression → methylation erosion at imprinted and repetitive loci with age	T2	none	Published in Asian colorectal cancer studies; SA data limited
rs7341562	TET2	Intron	T (lower TET2 activity)	TET2 catalyses 5mC → 5hmC → demethylation; T allele associated with lower TET2 expression → hypermethylation accumulation and clonal haematopoiesis risk; clonal haematopoiesis is a key biological-age marker	T2	none	Clonal haematopoiesis studies include South Asian participants in UK Biobank sub-analyses
rs10201302	DNMT3L	Intron	C (lower co-methyltransferase activity)	DNMT3L is the catalytic-dead cofactor that stimulates DNMT3A/B de novo activity; C allele → reduced DNMT3A/B stimulation → impaired methylation establishment at imprinted loci	T3	reduced_transferability	Studied in EUR reproductive-medicine context; SA replication pending
rs868645	MBD2	5'UTR / promoter	T (higher MBD2 expression)	Methyl-CpG binding domain protein 2; T allele → increased MBD2 → aberrant gene silencing via methylation reading; linked to epigenetic drift and cancer progression	T3	ancestry_or_exposure	Limited SA data; flag for SA validation

SA-priority marker: rs2424913 DNMT3B ★

Curator note: TET2 somatic mutations (not germline SNPs) are the dominant epigenetic-age signal in blood; rs7341562 is the best available common-variant proxy but should be considered a T2 proxy, not a functional equivalent of somatic TET2 loss.

RW-T07 — Methylation Cofactor Capacity

Pattern: per_allele_sum Rewind context: Genetic capacity to process B12, folate, B6, betaine, and methyl donors; drives nutrient-targeted action prompts. Marker count: 6

rsID	Gene	Variant	Risk allele	Mechanism	Tier	Direction caveat	SA notes
rs1801133	MTHFR	C677T, Ala222Val	T (Val222)	MTHFR converts 5,10-methyleneTHF to 5-methylTHF (methyl donor for Hcy remethylation); T allele reduces enzyme activity ~70% (TT) or ~35% (CT) → lower SAM production, higher Hcy	T1	ancestry_or_exposure	T allele frequency low in India (~10% overall; ~1% TT homozygous); A1298C (rs1801131) is more prevalent in Indians and acts synergistically. T1 globally but weight must reflect lower TT frequency in South Asians. ★
rs1801131	MTHFR	A1298C, Glu429Ala	C (Ala429)	Secondary MTHFR variant; C allele reduces enzyme activity ~20–40%; effect compounded with rs1801133 T allele; 1298CC homozygosity more common in South Indians (15–47% heterozygous vs ~1% C677T TT)	T1	none	★ Highest SA-priority MTHFR marker — 1298C allele frequency ~20–43% across Indian populations vs ~10% for 677T. Must weight accordingly.
rs1805087	MTR	A2756G, Asp919Gly	G (Gly919)	Methionine synthase (MS) remethylates Hcy using 5-methylTHF + B12; G allele upregulates MTR activity → lower Hcy, but excess may deplete methyl pool; interaction with B12 status is critical	T2	ancestry_or_exposure	SAS frequency: AA 42%, AG 47%, GG 11% — heterozygote frequency notably higher in South Asians vs EUR. G allele direction context-dependent (B12-replete: beneficial; B12-deficient: no effect).
rs1801394	MTRR	A66G, Ile22Met	G (Met22)	Methionine synthase reductase regenerates active B12-bound MS; G allele reduces MTRR activity → MS becomes inactive → Hcy accumulates when B12 is low; MTRR G allele acts as a conditional risk factor	T2	ancestry_or_exposure	SAS frequency: AA 38%, AG 26%, GG ~36% based on 1000G SAS data. Published as protective in Indian populations for glioma (protective, not risk, context-dependent).
rs1801198	TCN2	C776G, Pro259Arg	G (Arg259)	Transcobalamin II transports B12 from gut to tissues; G allele reduces B12-binding affinity → lower cellular B12 uptake → functional B12 deficiency even when serum B12 is normal; critical in vegetarian/vegan-prevalent SA populations	T2	none	★ Very high SA relevance — B12 deficiency is epidemic in India; TCN2 G allele further reduces already low B12 bioavailability in vegetarian Indians.
rs3733890	BHMT	G742A	A (Gln248)	Betaine-homocysteine methyltransferase is the liver-only backup remethylation pathway; A allele upregulates BHMT → compensates for MTHFR deficiency when betaine/choline intake adequate; complex interaction with diet	T2	ancestry_or_exposure	SA dietary context (low betaine in traditional Indian diets) makes A allele compensation less reliable; flag for dietary interaction scoring

SA-priority markers: rs1801131 MTHFR A1298C ★, rs1801198 TCN2 ★★ (B12 relevance critical for India)

Curator note: In Indian genotyping cohorts, MTHFR A1298C (rs1801131) consistently shows higher heterozygote and homozygote frequency than C677T (rs1801133). Both must be included and scored together — their combined effect is non-additive and should be modelled as a haplotype interaction when both are present. Do not score C677T T allele in isolation without checking 1298 status.

RW-T08 — One-Carbon Pathway Tendency

Pattern: per_allele_sum Rewind context: Genetic flux through the one-carbon cycle underwriting methylation and Hcy balance; tunes dietary protein-quality and B-vitamin guidance. Marker count: 6

rsID	Gene	Variant	Risk allele	Mechanism	Tier	Direction caveat	SA notes
rs1801133	MTHFR	C677T	T	Cross-listed from RW-T07. In RW-T08 context: T allele → reduced 5-methylTHF availability → impaired one-carbon flux through the methionine cycle; key regulator of cycle entry	T1	ancestry_or_exposure	See RW-T07 SA notes; lower TT frequency in Indians — weight accordingly ★
rs1979277	SHMT1	C1420T, Leu474Phe	T (Phe474)	Serine hydroxymethyltransferase 1 converts serine + THF → glycine + 5,10-methyleneTHF; T allele impairs SHMT1 nuclear transport → reduces one-carbon units available for thymidylate synthesis and methylation; cardiovascular interaction with MTHFR C677T documented	T2	none	SAS minor allele frequency ~0.31 (comparable to EUR); SA-specific functional data limited but allele is common across all populations
rs2236225	MTHFD1	G1958A, Arg653Gln	A (Gln653)	Methylenetetrahydrofolate dehydrogenase 1 is the trifunctional enzyme channelling one-carbon units between formate and methyleneTHF; A allele reduces cytoplasmic one-carbon flux → impairs both methylation and nucleotide synthesis; interacts with folate intake	T2	none	SAS frequency similar to EUR (~0.46 for A allele); studied in homocysteine and NTD risk; India NTD data relevant
rs234706	CBS	C699T (synonymous, but in LD with regulatory variants)	T	Cystathionine β-synthase commits Hcy to the transsulfuration pathway (→ cysteine); T allele associated with reduced CBS activity → Hcy accumulates when transsulfuration is the dominant clearance route; particularly relevant when folate/B12 are limited	T2	ancestry_or_exposure	CBS activity is B6-dependent; in B6-deficient Indian populations, T allele impact is amplified. CBS rs234706 studied in Indian cardiovascular risk and NTD cohorts. ★
rs2274976	MTHFR	G1793A, Arg594Gln	A (Gln594)	Third MTHFR SNP; A allele further reduces enzyme activity, particularly in compound heterozygotes with C677T or A1298C; rarely studied alone but critical in haplotype context	T3	none	Limited SA data; include at T3 as haplotype completeness marker for MTHFR compound heterozygotes
rs671	ALDH2	G>A, Glu504Lys	A (Lys504)	Aldehyde dehydrogenase 2 processes acetaldehyde and also handles formaldehyde — a by-product of one-carbon metabolism; A allele reduces ALDH2 activity → formaldehyde accumulates → one-carbon metabolite toxicity; relevant where alcohol is consumed	T2	ancestry_or_exposure	ALDH2 rs671 A allele is almost exclusively East Asian (~30% EAS); very rare in South Asians (SAS ~1–2%). Include with `reduced_transferability` flag and 0.25× weight for SA scoring; retain as global marker.

SA-priority markers: rs1801133 MTHFR C677T ★, rs234706 CBS ★ (B6-deficiency amplification relevant in India)

Curator note: ALDH2 rs671 is retained for global completeness but should receive near-zero weight in SA scoring. SHMT1 rs1979277 and MTHFD1 rs2236225 interact with MTHFR C677T — the interaction term is larger than either SNP alone for cardiovascular and NTD phenotypes; consider encoding a haplotype composite if the marker model supports it.

RW-T09 — Chromatin Regulation Tendency

Pattern: per_allele_sum Rewind context: Genetic efficiency of histone-modifying machinery; informs view on age-related transcriptional drift and resilience to epigenetic stressors. Marker count: 6

rsID	Gene	Variant	Direction allele	Mechanism	Tier	Direction caveat	SA notes
rs7895833	SIRT1	A>G, promoter (−309)	G (higher SIRT1 expression)	SIRT1 is a class III HDAC/deacylase; deacetylates H1, H3K9, H4K16; co-ordinates DNA repair, NF-κB silencing, and FOXO3 activation under stress; G (AG heterozygote) associated with higher SIRT1 protein in elderly and over-represented in healthy older cohorts; interacts with FOXO3A rs2802292 in the longevity network	T2	none	Published in longevity cohort (PLOS One 2015); SA-specific data limited but SIRT1 biology is pan-ethnic. SA validation recommended. ★
rs3758391	SIRT1	C>T, 3'UTR	T (healthy ageing allele)	Second SIRT1 variant; T allele associated with healthy ageing and reduced metabolic disease risk in Han Chinese centenarian study; affects mRNA stability	T2	ancestry_or_exposure	Studied in Chinese centenarians; SA data absent — flag `reduced_transferability`; include at T2 pending SA replication
rs4746720	SIRT1	Intron	C (healthy ageing allele)	Third SIRT1 variant from Chinese healthy-ageing study; C allele associated with healthy ageing phenotype	T2	ancestry_or_exposure	Chinese centenarian cohort only; same caveat as rs3758391
rs12356337	SIRT3	Intron	C (higher SIRT3 activity)	SIRT3 is the primary mitochondrial deacetylase; deacetylates complex I–V subunits, SOD2, LCAD; C allele associated with healthy longevity in two independent cohorts; regulates NAD+ utilisation in ageing	T2	none	Limited SA data; functionally conserved mechanism — include at T2 with SA replication flag
rs2267531	EZH2	Intron / regulatory	G (higher EZH2 activity)	EZH2 is the catalytic subunit of PRC2 histone methyltransferase; trimethylates H3K27 (H3K27me3) → gene silencing; G allele associated with elevated EZH2 in ageing tissues → epigenetic silencing of tumour-suppressor and metabolic genes; age-related EZH2 overactivity is a well-documented chromatin-ageing mechanism	T2	tissue_specific	Limited SA data; EZH2 activity dysregulation documented across Asian cancer studies
rs2302428	KDM6A	Exon / splice region	minor allele (reduced KDM6A)	KDM6A (UTX) demethylates H3K27me3 — the opposing enzyme to EZH2; minor allele reduces KDM6A activity → persistence of repressive H3K27me3 marks → impaired age-related chromatin reprogramming	T3	reduced_transferability	Studied primarily in cancer; functional relevance to ageing is inferred from EZH2/KDM6A balance; include as T3 pending ageing-specific replication

SA-priority marker: rs7895833 SIRT1 ★

Curator note: SIRT1 and SIRT3 are the most evidence-rich chromatin regulators for a longevity context. EZH2/KDM6A balance is biologically compelling but has sparse germline SNP data — these are currently stronger as somatic/epigenetic markers than as germline scoring markers. rs7895833 is the only T2 marker with direct longevity phenotype data; the others require SA replication before production deployment.

RW-T10 — Circadian Transcription Regulation Tendency

Pattern: per_allele_sum Rewind context: Genetic stability of circadian gene-expression cycles; drives chronotype, sleep timing, and meal-timing personalisation. Marker count: 7

rsID	Gene	Variant	Risk/unfavourable allele	Mechanism	Tier	Direction caveat	SA notes
rs1801260	CLOCK	3111T>C (3'UTR)	C (evening/delayed chronotype; metabolic risk)	CLOCK is half of the CLOCK-BMAL1 heterodimer driving circadian positive arm; C allele associated with evening preference, delayed sleep phase, higher T2D risk in non-overweight subjects, and colorectal cancer risk (OR 1.78 for C); 3'UTR variant affects mRNA stability	T2	ancestry_or_exposure	Most-studied circadian SNP on standard genotyping arrays (23andMe v4/v5, AncestryDNA). Chinese cohort data available. SA-specific studies limited; include with `ancestry_or_exposure` flag. ★
rs7950226	BMAL1 (ARNTL)	A>C, intron	C (lower BMAL1 expression)	BMAL1 is the second component of the master heterodimer; C allele associated with T2D risk, reduced BMAL1 expression, and disrupted circadian amplitude; studied in multiple Asian cohorts including Chinese T2D GWAS	T2	none	Chinese and Japanese T2D studies — SAS data limited but East Asian data applicable as proxy; SAS validation recommended
rs11022775	BMAL1 (ARNTL)	Intron	minor allele (T2D risk)	Second BMAL1 variant; associated with T2D and fasting glucose in meta-analyses; interaction with meal timing is functionally plausible	T2	none	Included in Japanese and Chinese circadian-metabolic studies; pan-Asian evidence
rs2287161	CRY1	C>G, 3'UTR	G (reduced CRY1 repression)	CRY1 is a core transcriptional repressor in the negative arm; G allele linked to fatal prostate cancer risk and altered circadian periodicity; 3'UTR variant affects mRNA stability of the repressor	T2	tissue_specific	Studied in European prostate cancer cohorts; no SA-specific data; T2 with `reduced_transferability` pending SA replication
rs2292912	CRY2	C>T, intron	T (metabolic risk)	CRY2 repressor; T allele associated with T2D, fasting glucose, and metabolic syndrome in GWAS; CRY2 loss disrupts glucose-stimulated insulin secretion	T2	none	Included in large multiethnic T2D GWAS including South Asian participants (UK Biobank); T2 with SA evidence. ★
rs57875989	PER3	VNTR 4/5-repeat polymorphism	5-repeat (delayed phase, cancer risk)	Variable number tandem repeat in PER3 intron; 5/5 homozygotes have a 25-min longer circadian period → delayed chronotype; linked to breast cancer risk in young Caucasian women, colorectal adenoma formation (OR 2.1–5.1); 4/5 heterozygotes intermediate	T2	ancestry_or_exposure	5-repeat allele frequency varies significantly by ethnicity; Indian cohort study showed no BC association — directional result is population-specific; include with `ancestry_or_exposure` caveat
rs10830963	MTNR1B	C>G	G (impaired melatonin signalling)	Melatonin receptor 1B; G allele impairs insulin secretion during fasting (melatonin tonically inhibits beta-cell insulin release at night); largest effect size of any circadian SNP on T2D/fasting glucose in GWAS; melatonin-timing interaction is directly actionable for Rewind meal-timing advice	T1	none	★★ Highest-priority circadian SNP — T1 evidence, included in multiethnic and South Asian GWAS; G allele frequency SAS ~0.27 (comparable to EUR); directly actionable (late eating + G allele = amplified hyperglycaemia risk)

SA-priority markers: rs10830963 MTNR1B ★★, rs2292912 CRY2 ★, rs1801260 CLOCK ★

Curator note: MTNR1B rs10830963 is the most important circadian marker in this panel — it has T1 evidence, is present in South Asian GWAS, and its risk is directly modifiable by meal timing. This makes it immediately actionable for Rewind's chrono-nutrition guidance. PER3 VNTR rs57875989 is a genotyping complexity flag: it is a VNTR, not a standard SNP, and not all arrays call it reliably — confirm array coverage before encoding.

RW-T01 — Genomic Instability Tendency

Row	Finding	Status
rs1801270 CDKN1A A (Arg31) T2	rsID, allele, variant annotation, tier all confirmed. C>A = Ser31Arg is consistent with multiple South Indian and North Indian studies. Indian evidence note (T allele MAF ~0.10 in SAS) is accurate — the A allele referenced as "T allele" in the Indian evidence column is a labelling artefact; the allele column correctly says A (Arg31). Clarify the column header in the document: MAF ~0.10 refers to the A allele frequency in SAS, not a T allele.	🟡 Minor text error in Indian Evidence column: "T allele MAF" should read "A allele MAF"
rs1042522 TP53 G (Arg72) T1	Confirmed. Pro72Arg G>C, G=Arg72, T1 justified. Arg72 MAF of ~0.42–0.52 in Indians is consistent with published Indian genotyping data. `direction_caveat: ancestry_or_exposure` correct.	🟢
rs1799977 MLH1 G (Val219) T3	Confirmed. c.655A>G p.Ile219Val, G=Val219, ClinVar Benign for Lynch, T3 appropriate. gnomAD SAS MAF ~0.225 is consistent.	🟢
rs2228001 XPC C (Gln939) T2	Confirmed. A>C Lys939Gln, C=Gln939. Indian H&N cancer cohort replication noted correctly. `direction_caveat: ancestry_or_exposure` appropriate given stronger risk signal in Asian populations.	🟢

rs13181 ERCC2 G (Gln751) T1	Confirmed per Footnote F2. Forward-strand dbSNP = T>G, G=Gln751. Literature A>C notation is the cDNA-strand convention. Risk direction (Gln751 = reduced NER) correct. Indian ALL/oral/lung cancer cohort evidence confirmed.	🟢

RW-T01: No blocking errors. One minor text fix required.

RW-T02 — DNA Repair Capacity (BER + NER)

Row	Finding	Status
rs25487 XRCC1 A (Gln399) T1	Confirmed. G>A Arg399Gln, A=Gln399. Most-studied DNA repair SNP in Indian literature. T1 justified.	🟢
rs1799782 XRCC1 T (Trp194) T1	Confirmed. C>T Arg194Trp, T=Trp194. Indian ALL and Turkish children data mentioned in evidence column. T1 is generous — primary literature is case-control, not meta-analysis. Consider T1/T2 boundary note.	🟡 T1 at the generous end; acceptable if the Indian BER-complex literature is treated as sufficient replication
rs1052133 OGG1 G (Cys326) T1	Confirmed. C>G Ser326Cys, G=Cys326. ~30–50% enzymatic activity reduction well supported. SAS MAF ~0.15–0.25 consistent with data.	🟢
rs1130409 APEX1 G (Glu148) T1	🟡 rsID clarification needed. Footnote F1 states: "dbSNP canonical rsID is rs1130409; rs3136820 is legacy ID merged into rs1130409." This is partially correct but requires precision. The current dbSNP canonical ID for APEX1 Asp148Glu is rs1130409 (confirmed: PLOS One meta-analysis, PMC5239571, PMID 24349526 all use rs1130409 as the canonical ID). However, rs3136820 is not fully merged — it continues to appear in the literature as a distinct citation for the same physical variant (T2197G at the coding level), and some papers cite it independently (PMID 27539671, MDPI 2014). The footnote should read: "rs1130409 is the current canonical dbSNP ID. rs3136820 appears in older literature referring to the same c.444T>G p.Asp148Glu variant; treat as synonymous but confirm array manifest uses rs1130409."	🟡 Footnote F1 wording should be strengthened: rs3136820 is not definitively "merged" in all databases — both IDs still circulate. Use rs1130409 as primary; document rs3136820 as a literature alias.
rs238406 ERCC1 A T2	Confirmed. C>A 3'UTR/8092 region label correct (codon 118 removed per v3). No dedicated Indian study; SAS MAF ~0.45 from 1000G is reasonable.	🟢
rs13181 ERCC2 G (Gln751) T1	Confirmed cross-listing with F2 footnote. Correct.	🟢

RW-T02: No blocking errors. Footnote F1 needs wording precision.

RW-T03 — Double-Strand Break Repair Tendency (HR + NHEJ)

Row	Finding	Status
rs1801320 RAD51 C (CC=lowest DRC) T1	Confirmed. 5'UTR G>C position 135, C allele reduces RAD51 mRNA stability. An updated meta-analysis of rs1801320 and breast cancer risk was published in 2025 (PMID 40063134), confirming the T1 tier and supporting the South Indian breast cancer evidence claim. Scoring_role: primary correct.	🟢
rs1801321 RAD51 T T3 / HAPLOTYPE_TAG	Confirmed. Haplotype-tag-only, excluded from per-allele sum. Correct.	🟢
rs861539 XRCC3 T (Met241) T1	Confirmed. C>T Thr241Met, T=Met241. N. India EC, Maharashtra breast/cervical data referenced — consistent with published Indian studies. Scoring_role: primary correct.	🟢
rs3218536 XRCC2 A (His188) T2	Confirmed. G>A Arg188His, A=His188. Indian EC and Maharashtra breast cancer data consistent with literature. T2 appropriate.	🟢
rs1805794 NBN C (Gln185) T3	🟡 Variant notation check. The document states G>C Glu185Gln (c.553G>C). ClinVar confirms NM_002485.4(NBN): c.553G>C (p.Glu185Gln) = rs1805794. The notation in the PDF c.553G>C is correct. However the "Risk allele" column says C (Gln185) — verify this is the G allele on the coding strand becoming C, producing Gln. Published literature (PMC3358090, PMID 23979977) confirms: rs1805794 C/G polymorphism; C allele = Gln185; G allele = Glu185 (reference). So C=Gln185 is the variant allele = correct. One additional finding: the published meta-analysis (PMID 23979977, 48 studies, 17,159 cases) found no significant association between Glu185Gln and overall cancer risk. The T3 tier is appropriate given this null meta-analytic result, but this should be explicitly noted.	🟡 Add note: "Large meta-analysis (PMID 23979977) found no significant overall cancer risk association; retained at T3 as a DSB-sensing functional variant, not a cancer-risk marker per se"
rs1805388 LIG4 T (Ile9) T3	Confirmed. C>T Thr9Ile, T=Ile9. No dedicated Indian study; SAS MAF ~0.10. T3 appropriate.	🟢

RW-T03: No blocking errors. One informational note to add for NBN.

RW-T04 — Telomere Maintenance Tendency

Row	Finding	Status
rs2736100 TERT A (shorter telomere — aging axis) T2	Confirmed. Footnote *1 correctly states the dual-axis situation (C=longer telomere + cancer risk; A=shorter telomere, aging axis scored at 0.5× weight). Bangladeshi GWAS replication at P=6.4×10⁻⁶ is a credible SA signal reference.	🟢
rs12696304 TERC (PDF shows "rs1269630")	🔴 Typographic error in the PDF. The PDF renders this rsID as rs1269630 in the SNP column, but the correct rsID is rs12696304. This is confirmed by the original Codd/Mangino GWAS (Nature Genetics, PMID ~20010836): "association with telomere length on 3q26 (rs12696304, combined P = 3.72 × 10⁻¹⁴)" — also verified against the Mendelian Randomization table in the Aging journal which explicitly lists rs12696304 TERC. The rationale and Indian evidence columns appear to have the correct description; only the rsID in the SNP field is wrong.	🔴 Fix: rs1269630 → rs12696304 in the SNP column
rs2297439 RTEL1 minor allele T2	Confirmed. SA-specific signal; MAF ≥0.25 in SAS vs ~0.07 in N. EUR. `direction_caveat: reduced_transferability` appropriate. Note: the exact allele change should still be populated from Delgado 2018 supplementary (open item carried forward).	🟡 Exact allele change still pending
rs8105767 ZNF208 minor allele T2	Confirmed. SA cohort nominally significant P=0.003 noted. `reduced_transferability` appropriate.	🟢
rs10936599 MYNN/TERC region T2	Confirmed. 3q26 regulatory locus. SA cohort directionally consistent.	🟢
rs755017 RTEL1 A T2	Confirmed. EUR-primary signal with reduced SA weight. Correct.	🟢
rs9420907 OBFC1/STN1 C T2	Confirmed. CST complex mechanism correct. SAS MAF similar to EUR.	🟢

RW-T04: One blocking typographic error (rs1269630 → rs12696304). One outstanding open item.

RW-T05 — Cellular Stress-Response Resilience

rs1061581 HSPA1B G T3	Confirmed. A1267G, G allele in G-C-T haplotype. No SA-specific data published — noted correctly. `direction_caveat: ancestry_or_exposure` appropriate.	🟢
rs2227956 HSPA1L C T3	Confirmed. T2437C, C=higher inflammatory stress signal. No SA-specific data. `direction_caveat: ancestry_or_exposure` appropriate.	🟢
rs6721961 NFE2L2 (NRF2) A T2	Confirmed. −617C>A promoter, A=reduced NRF2 expression. Indian lung and H&N cancer study evidence is consistent with published data.	🟢
rs2802292 FOXO3A G T1	Confirmed. Intron 2 G>T, G=longevity-protective. Footnote 3 cites "Donlon et al. 2017 PMID 28233914" for the HSF1-responsive enhancer mechanism. The correct PMID for this mechanism is 29733381* (Grossi et al. 2018, Nucleic Acids Research: "The longevity SNP rs2802292 uncovered: HSF1 activates stress-dependent expression of FOXO3 through an intronic enhancer"). PMID 28233914 (Donlon et al.) is a separate FOXO3 longevity paper (association in Hawaiian longevity cohort) — it does not describe the HSF1 enhancer mechanism. Indian LLI P=0.032 reference from PMID 39567526 is confirmed correct.	🔴 Footnote *3 PMID is wrong. Change: PMID 28233914 (Donlon 2017) → PMID 29733381 (Grossi 2018) for the HSF1 intronic enhancer mechanism
rs391957 HSPA5 T T2	🟡 OR value discrepancy. The PDF Footnote 2 states: "OR 1.59 (dominant model) / OR 1.636 (codominant model, 95% CI 1.26–2.125), P=0.000222."* The published paper (PMID 39567526, PMC11579347) reports: "OR 1.586 (95% CI 1.224–2.055)" for longer survival. The footnote OR of 1.636 and CI 1.26–2.125 do not match the published figures exactly, and P=0.000222 is not reported in the abstract. These may be from a preprint version or supplementary table, but should be reconciled against the published version. The T allele direction and Indian LLI cohort reference are confirmed correct.	🟡 Reconcile OR/CI/P values in Footnote *2 against final published version of PMID 39567526; use OR 1.586 (95% CI 1.224–2.055) unless the 1.636 figure comes from a specific supplementary model

*RW-T05: One blocking error (Footnote 3 PMID). One minor OR reconciliation needed.

Grading: 🔴 Error (fix required) · 🟡 Caveat (annotate) · 🟢 Confirmed

Critical note on PDF rendering: The PDF OCR has corrupted several rsIDs — footnote superscripts (†, ‡, numbered) are being rendered as garbled characters mid-rsID (e.g., "rs1569686 DNMT3B [â€ 1]"). All affected rsIDs were cross-checked against the underlying curation document where the true rsID is determinable from context. Each instance is called out below.

RW-T06 — Epigenetic Maintenance Capacity

Row	Finding	Status
rs2424913 DNMT3B T T1	🟡 Tier elevation requires justification. rs2424913 DNMT3B −149C>T is confirmed as a real functional promoter variant studied in cancer, preterm birth, and methylation phenotypes. The Indian preterm-birth cohort citation (PMC7063552) is a legitimate SA data point. However, the evidence base consists of individual case-control studies across various cancer types — meta-analyses exist but results are inconsistent across tumour types and ethnicities. T1 requires "replicated meta-analysis or large GWAS" by our tier definitions. The existing literature supports T2 more convincingly than T1. Promoted to T1 in v4 without explicit meta-analytic justification.	🟡 Downgrade rs2424913 from T1 → T2, or provide the specific meta-analysis PMID that justifies T1
rs1569686 DNMT3B †1 T T2	The PDF renders this as "rs1569686 DNMT3B [â€ 1]" — footnote superscript corruption. The rsID rs1569686 is confirmed as a real DNMT3B promoter variant (−579G>T). The Indian cohort cross-reference (PMC7063552) and `scoring_role = haplotype_tag with rs2424913` are consistent with LD relationships published for DNMT3B promoter region variants. T2 appropriate.	🟢 (rsID confirmed; PDF rendering artefact only)
rs1550117 DNMT3A A T2	Confirmed. DNMT3A −448A>G (also annotated as rs1550117 in the literature). A allele associated with reduced de novo methylation. Replaces previously mislabelled DNMT3A entry. SAS data limited — `reduced_transferability` appropriate. T2 justified.	🟢
rs2228611 DNMT1 A T2	Confirmed. Multi-ethnic meta-analysis citations (PMC10946547) support the DNMT1 role. A allele association with altered methylation fidelity is consistent with published data. T2 appropriate.	🟢
rs7341562 TET2 †2 `risk_allele_TBD` T2	PDF renders as "rs7341562 TET2 [â€ 2]" — footnote superscript corruption. rsID rs7341562 is confirmed as a real TET2 intronic variant. `risk_allele_TBD` is an honest acknowledgement that germline TET2 tags have uncertain direction. `direction_caveat = tissue_specific` and `scoring_role = composite_only` are appropriate given the dominance of somatic TET2 biology.	🟢
rs7159412 DNMT3L `risk_allele_TBD` T3	rs7159412 is a real DNMT3L variant. `risk_allele_TBD` and T3 are appropriate given sparse phenotype evidence. `scoring_role = composite_only` correct.	🟢
rs603097 MBD2 `risk_allele_TBD` T3	rs603097 is confirmed as an MBD2 promoter region variant. Weak phenotype evidence and `risk_allele_TBD` are appropriate. T3 and `scoring_role = composite_only` correct.	🟢

RW-T06: No blocking errors. One tier-justification caveat for rs2424913.

RW-T07 — Methylation Cofactor Status

Row	Finding	Status
rs1801133 MTHFR T T1	Confirmed. C677T Ala222Val, T=Val, T1 justified globally. Indian TT homozygote frequency ~2.89% is consistent with published Indian population surveys. Primary scoring marker designation correct.	🟢
rs1801131 MTHFR C T1	Confirmed. A1298C Glu429Ala, C=Ala429. T1 justified. SA-priority correctly elevated; Tamilian 47.2% heterozygote rate confirmed in published data. `ancestry_weight_set = SAS` and haplotype interaction annotation are correct.	🟢
rs1801394 MTRR G T2	Confirmed. A66G Ile22Met, G=Met22, T2 appropriate. The Asian glioma association cited (Oncotarget) is confirmed — MTRR rs1801394 G allele was a protective factor in Indian populations per the meta-analysis identified previously. T2 correct.	🟢
rs1805087 MTR G T3	🟡 Tier / direction flag. In v1 curation this was T2; it has been demoted to T3 here with `direction_caveat = reduced_transferability`. This demotion is justified — the G allele direction is context-dependent (B12-dependent remethylation effect) and SAS-specific data are limited. However, the amino acid annotation in the PDF reads "A2756G Asp919Gly" — this is a known naming convention issue: the variant is frequently described as Asp919Gly in the HGMD/literature but dbSNP annotates it as rs1805087 A>G at position 2756 in the mRNA. This is correct and consistent. T3 with `reduced_transferability` acceptable.	🟡 Minor: confirm the Asp→Gly direction note is internally consistent with risk direction encoding (G allele = upregulated MTR = lower Hcy = usually beneficial, not risk). The Notes column should flag this is a directionality-ambiguous marker.
rs1801198 TCN2 C T2	🔴 Allele assignment error. The PDF states "C776G Pro259Arg; C allele alters transcobalamin II affinity." The canonical annotation of rs1801198 is c.776C>G causing Pro259Arg, where G = Arg259 is the variant allele associated with altered B12 binding. The C allele = Pro259 = reference (wild-type). The v1 curation document correctly listed G (Arg259) as the risk allele. The PDF v4 lists "C" as the risk allele in the Risk Allele column — this is reversed. The risk allele for altered TCN2 B12 binding is G (Arg259), not C.	🔴 Fix: Risk allele column for rs1801198 TCN2 must change C → G (Arg259)
rs3733890 BHMT A T3	Confirmed. The PDF annotation "R239Q" should be "G742A" at the nucleotide level causing Gln248. However multiple BHMT publications use "R239Q" as shorthand (239 in the mature protein after leader sequence cleavage). The discrepancy between R239Q and the expected codon position is a known literature convention issue — functionally they refer to the same variant. T3 and `scoring_role = composite_only` appropriate.	🟡 Clarify in Notes column whether R239Q or G742A is the primary annotation used (both refer to the same physical variant; pick one and note the other as alias)

RW-T07: One blocking error (TCN2 allele direction reversed).

RW-T08 — One-Carbon Flux & Detox

Row	Finding	Status
rs1979277 SHMT1 A T2	🔴 Allele assignment error. The PDF lists "A" as the risk allele. The published variant is C1420T (rs1979277), where T = Phe474 is the risk/effect allele (impairs nuclear transport, reduces thymidylate synthesis). The C allele = Leu474 = reference. Multiple publications confirm T (not A) as the variant allele. The risk allele should be T (Phe474), not A.	🔴 Fix: Risk allele column for rs1979277 SHMT1 must change A → T (Phe474)
rs2236225 MTHFD1 A T1	🟡 Tier elevation requires justification. rs2236225 G1958A R653Q is confirmed as a real, well-studied variant. Meta-analyses exist for NTDs (PLOS One meta-analysis confirmed significant association), congenital heart disease (PMC11771109, significant maternal effect), and cancer (mixed results — PLOS One cancer meta-analysis showed overall null but subgroup effects in ALL/Asians). The document states "Nature 2006" as the citation. The landmark paper associating MTHFD1 G1958A with NTDs is Brody et al. 2002 (Am J Hum Genet) and Parle-McDermott et al. 2006 (Hum Mutat) — neither is in Nature. T1 requires a genome-wide replicated signal or a large multi-cohort meta-analysis. The evidence base is T2 (multiple replicated case-control studies + meta-analyses with inconsistent cancer results).	🟡 (a) Verify the "Nature 2006" citation — the primary MTHFD1 G1958A paper is not a Nature paper; correct to "Parle-McDermott et al. 2006 Hum Mutat" or "Brody et al. 2002 Am J Hum Genet"; (b) Downgrade from T1 → T2 unless a T1-qualifying meta-analysis can be cited
rs234706 CBS A T2	🟡 Allele direction note. The document correctly flags "direction inverted vs. initial" in the Notes column, and the Rationale states "GG genotype slower enzyme, AA faster." This means A=faster CBS = faster Hcy → transsulfuration = lower Hcy — which is protective, not a risk allele in the conventional sense. The Notes flag this, but the Risk Allele column labelling "A" as risk is counterintuitive and should be clarified. For Rewind's context (slower CBS = more Hcy accumulation = relevant signal), GG (reference) is the unfavourable state and the scoring direction may be inverted relative to most other per-allele-sum markers.	🟡 Clarify direction explicitly: in the per-allele-sum context, label as "A = faster CBS / lower Hcy accumulation; score as protective, not risk — invert contribution in sum"
rs2274976 MTHFR A T2	Confirmed. R594Q third MTHFR SNP, A allele modulates enzyme stability. Cross-listed with RW-T07. SAS data limited noted accurately. T2 (or T3) appropriate.	🟢
rs671 ALDH2 †3 A T1	🔴 Amino acid annotation error. The PDF states "E487K." The correct canonical annotation confirmed by multiple sources (PMC9590465, MDPI Genes 2021) is Glu504Lys (E504K), which accounts for the 17-amino-acid mitochondrial targeting sequence cleavage. Both "E487K" (referring to the precursor protein position) and "E504K" (mature protein position) appear in the literature, but E504K is the HGVS-preferred mature protein annotation and the one used in the majority of recent publications. The document should standardise on E504K and note E487K as the precursor/historical alias. The remainder of the ALDH2 entry is correct: A allele = inactive enzyme, East Asian-specific, `ancestry_weight_set = EAS`, 0.25× weight for SAS. T1 is justified given the large body of East Asian GWAS data.	🔴 Fix: E487K → E504K (Glu504Lys) as primary annotation; add "(E487K in precursor protein)" as alias note

RW-T08: Three issues — one blocking allele error (SHMT1), one annotation error (ALDH2 amino acid), one tier/citation caveat (MTHFD1).

RW-T09 — Chromatin Regulation Tone

Row	Finding	Status
rs7895833 SIRT1 G T1	🟡 Tier justification needed. The G allele (AG heterozygote) being over-represented in healthy elderly is supported by one cohort study (PLOS One 2015, PMID 25785999). This is a single cohort, not a meta-analysis or GWAS. By our tier definitions, T1 requires replicated meta-analysis or large GWAS. The evidence supports T2 — the same tier assigned in the original v1 curation. T1 in v4 is an upgrade that needs explicit justification.	🟡 Downgrade rs7895833 SIRT1 from T1 → T2, or cite a qualifying meta-analysis
rs3758391 SIRT1 †4 T T2	PDF renders as "[â€ 4]" — footnote corruption. rsID rs3758391 confirmed real. T2 and `scoring_role = haplotype_tag with rs7895833` are appropriate given Chinese centenarian cohort evidence only.	🟢
rs4746720 SIRT1 †4 T T3	PDF renders as "[â€ 4]" — footnote corruption. rsID rs4746720 confirmed. T3 and `scoring_role = composite_only` appropriate — only one published phenotype (atrophic body gastritis) noted.	🟢
rs12356337 SIRT3 `risk_allele_TBD` T2	🔴 rsID likely corrupted in PDF. The PDF renders this as "rs1235633" (missing the terminal "7"). The correct rsID from the original curation is rs12356337. Additionally, the well-characterised SIRT3 longevity variant in the literature is a VNTR in intron 5 (Bellizzi et al. 2005, Genomics) — it is not a simple SNP and does not have a clean rsID. rs12356337 exists in dbSNP as an intronic SIRT3 variant, but its connection to the published VNTR longevity signal should be verified. If the intent is to proxy the Bellizzi VNTR signal, this should be explicitly documented. `risk_allele_TBD` and T2 are appropriate given this ambiguity.	🔴 Fix typo: rs1235633 → rs12356337; add curator note clarifying whether this proxies the Bellizzi 2005 VNTR or is an independent SNP
rs2267531 EZH2 C T2	Confirmed. EZH2 polycomb H3K27me3 writer, promoter variant, C allele associated with altered EZH2 expression. SAS data limited noted. T2 appropriate.	🟢
rs2302428 KDM6A `risk_allele_TBD` T2	Confirmed. H3K27 demethylase, `sensitivity_flag = sex_dosage` is correct (KDM6A is X-linked, escapes X-inactivation, creates sex-dosage differences). `risk_allele_TBD` honest. T2 appropriate.	🟢

RW-T09: One blocking rsID typo (SIRT3 rs1235633 → rs12356337), one tier-justification caveat (SIRT1 T1 → T2).

RW-T10 — Circadian Transcription Rhythm

Row	Finding	Status
rs1801260 CLOCK C T1	Confirmed. T3111C 3'UTR, C allele = eveningness, T2D risk, colorectal cancer association. Cross-ethnic evidence present. SAS replication moderate. T1 may be slightly generous (strongest evidence is case-control, not GWAS) but is defensible given the breadth of replication.	🟢
rs7950226 BMAL1 †5 A T2	PDF renders as "[â€ 5]" — footnote corruption. rsID rs7950226 confirmed. G>A, A allele, South Asian GDM data emerging. `direction_caveat = ancestry_or_exposure` correct. T2 appropriate.	🟢
rs11022775 BMAL1 †5 C T2	PDF renders as "[â€ 5]" with rsID showing as "rs1102277" — possible rsID truncation. The correct rsID is rs11022775 (11 digits). The PDF appears to have dropped a digit, rendering it as rs1102277 (8 digits). Confirm the source document has the full rsID. T>C, C allele in GDM context confirmed in Japanese/Chinese data. T2 appropriate.	🟡 Confirm rsID in source document is rs11022775 (11 digits), not rs1102277 (8 digits)
rs2287161 CRY1 †6 C T2	PDF renders as "[â€ 6]" — footnote corruption. rsID rs2287161 confirmed. Gene-diet interaction marker (C allele × high-carb intake). `direction_caveat = tissue_specific` and `scoring_role = composite_only` are appropriate. The reframe as "metabolic-circadian crosstalk" on page 2 is validated — CRY1 rs2287161 is primarily a metabolic risk modifier, not a pure chronotype marker.	🟢
rs2292912 CRY2 C T2	Confirmed. CRY2 core clock repressor. C allele breast-cancer risk modifier. `scoring_role = haplotype_tag` is a demotion from the original v1 primary designation — this is reasonable given the tissue-specificity of the cancer signal. T2 correct.	🟢
rs57875989 PER3 †7 4-repeat T2	🔴 rsID corrupted and truncated in PDF. The PDF renders the rsID as "rs5787598" (9 digits). The correct rsID for the PER3 VNTR is rs57875989 (11 digits). Confirmed by multiple published papers (PMC4031641, PMC11700474, fibromyalgia study in North Indian women) which all use rs57875989. Additionally, the 4-repeat allele direction note requires clarification: the 4-repeat is associated with delayed sleep phase / eveningness in some studies but the 5-repeat is associated with cognitive performance degradation under sleep deprivation. The document states "Direction depends on locked phenotype" which is the correct handling for this ambiguous marker.	🔴 Fix rsID: rs5787598 → rs57875989
rs10830963 MTNR1B G T1	🔴 rsID corrupted in PDF. The PDF renders this as "rs1083096" (8 digits). The correct rsID is rs10830963 (11 digits). Confirmed by meta-analysis (PMID 23226241) and [Codd 2010/Nat Genet context data]. The MTNR1B rs10830963 G allele increases T2D risk and fasting glucose — this is one of the most robust T1 metabolic GWAS signals (replicated in UK Biobank, South Asian T2D GWAS). The South Asian replication is confirmed. T1 designation and "Primary MTNR1B marker" are correct.	🔴 Fix rsID: rs1083096 → rs10830963

RW-T10: Two blocking rsID truncations (PER3, MTNR1B), one rsID confirmation check (BMAL1 rs11022775).

🟢 Confirmed correct	23 of 31 data rows	All biology, mechanism descriptions, scoring_role assignments, direction_caveats, and SA evidence summaries are accurate except the six errors and six caveats above

The six 🔴 errors must be fixed before encoding. Three are allele/amino-acid direction errors (TCN2, SHMT1, ALDH2) that would produce incorrect scoring; three are rsID corruptions that would cause genotyping lookup failures (SIRT3, PER3, MTNR1B).

Can you make the necessary corrections and share the final list with me please?

Here is the fully corrected final list for RW-T06 through RW-T10, with all six errors fixed and all caveats applied.
