What the study found

Who was studied 575,531 European ancestry individuals.

The effect Each copy of the T allele shifted the measure 0.0137 lower (95% confidence interval 0.0097-0.0176); p = 1 × 10−11.

Where it sits Chromosome 19, band 19q13.32 — a synonymous change in ERCC2.

What ClinVar records

Classification Benign/Likely benign for Xeroderma pigmentosum, group D, Cerebrooculofacioskeletal syndrome 2, Trichothiodystrophy 1, photosensitive; criteria provided, multiple submitters, no conflicts (2 of 4 stars, 11 submitters), last evaluated 2026-02-04. ClinVar record 256021 NM_000400.4(ERCC2):c.468A>C (p.Arg156=)

What this is ClinVar's aggregate record for this position (as of its 2026-10-19 release), not a result about you. A classification describes the variant against the condition named, as laboratories submitted it. Whether a person carries this variant, and what that would mean for them, is a question for a clinical test and a genetic counsellor.

What each result means

G/G No copy of the version the research linked to C-reactive protein levels (MTAG). This is the starting point the study compared everyone against.
G/T One copy of the version the research linked to C-reactive protein levels (MTAG). That is a smaller link than two copies.
T/T Two copies of the version the research linked to C-reactive protein levels (MTAG). That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs238406

What is rs238406?

rs238406 is a single position in the genome, in or near the ERCC2 gene. Published research associates it with c-reactive protein levels (mtag). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs238406 linked to?

On MyGeneLog this position is linked to C-Reactive Protein Levels. The research behind each link, and its sources, are set out on that condition page.

Does having rs238406 mean I will get this?

No. Common variants like this one move a probability slightly and, on their own, rarely decide anything about one person. Nothing on this page is a diagnosis, and health decisions should be made with a clinician who can see your whole picture.

Where does the information about rs238406 come from?

GWAS Catalog, Nature communications 2022, PMID:36376304. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
