OVOL2 · rs45473509

What the study found

Who was studied 544,127 European ancestry individuals.

The effect Each copy of the G allele shifted the measure 0.108 SD unit lower (95% confidence interval 0.081-0.134); p = 1 × 10−15.

How common The G allele had a frequency of about 1% in the people studied.

Where it sits Chromosome 20, band 20p11.23 — in an intron of OVOL2.

What each result means

A/A Published research associates this genotype with typical/baseline likelihood of Mean corpuscular volume — no copies of the reported risk allele.
A/G Published research associates this genotype (one copy of the reported risk allele) with an intermediate association with Mean corpuscular volume.
G/G Published research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Mean corpuscular volume compared to the general population.

Questions about rs45473509

What is rs45473509?

rs45473509 is a single position in the genome, in or near the OVOL2 gene. Published research associates it with mean corpuscular volume. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs45473509 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 rs45473509 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.
