Who was studied 38,000 South Asian ancestry individuals.
The effect
Each copy of the A allele shifted the measure 0.069 higher (95% confidence interval 0.053-0.085); p = 1 × 10−18.
Where it sits Chromosome 11, band 11p15.4 — between genes, 1.6 kb from OR51A9P.
What each result means
A/ATwo copies of the version the research linked to Mean corpuscular volume. That is the strongest link of the three results. A link in a study is not a diagnosis.
A/COne copy of the version the research linked to Mean corpuscular volume. That is a smaller link than two copies.
C/CNo copy of the version the research linked to Mean corpuscular volume. This is the starting point the study compared everyone against.

Questions about rs7934446
What is rs7934446?
rs7934446 is a single position in the genome, in or near the near OR51A9P 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.
What conditions is rs7934446 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 rs7934446 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 rs7934446 come from?
GWAS Catalog, Nature communications 2024, PMID:39414775. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
