Where this position leads

What the study found

Who was studied 460,935 European ancestry individuals.

The effect Each copy of the A allele shifted the measure 0.0463 SD unit higher (95% confidence interval 0.04-0.053); p = 6 × 10⁻⁴¹.

How common The A allele had a frequency of about 92% in the people studied.

Where it sits Chromosome 7, band 7q36.1 — in an intron of XRCC2.

What each result means

A/A Two copies of the version the research linked to Mean platelet volume. That is the strongest link of the three results. A link in a study is not a diagnosis.

A/G One copy of the version the research linked to Mean platelet volume. That is a smaller link than two copies.

G/G No copy of the version the research linked to Mean platelet volume. This is the starting point the study compared everyone against.

Questions about rs3218455

What is rs3218455?

rs3218455 is a single position in the genome, in or near the XRCC2 gene. Published research associates it with mean platelet volume. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs3218455 linked to?

On MyGeneLog this position is linked to Blood Cell Counts. The research behind each link, and its sources, are set out on that condition page.

Does having rs3218455 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 rs3218455 come from?

GWAS Catalog, Cell 2020, PMID:32888493. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
