Where this position leads

What the study found

Who was studied 22,639 European ancestry female cases, 1,080,289 European ancestry female controls, 22,639 African ancestry female cases, 1,080,289 African ancestry female controls, 22,639 Hispanic or Latin American female cases, 1,080,289 Hispanic or Latin American female controls, 22,639 East Asian ancestry female cases, 1,080,289 East Asian ancestry female controls, 22,639 South Asian ancestry female cases, 1,080,289 South Asian ancestry female controls.

The effect Each copy of the G allele carried 1.07 times the odds of Aortic stenosis (95% confidence interval 1.05-1.09); p = 1 × 10⁻¹¹.

How common The G allele had a frequency of about 42% in the people studied.

Where it sits Chromosome 3, band 3q26.2 — in an intron of MECOM.

What each result means

A/A No copy of the version the research linked to Aortic stenosis. This is the starting point the study compared everyone against.

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

G/G Two copies of the version the research linked to Aortic stenosis. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs2421650

What is rs2421650?

rs2421650 is a single position in the genome, in or near the MECOM gene. Published research associates it with aortic stenosis. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs2421650 linked to?

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

Does having rs2421650 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 rs2421650 come from?

GWAS Catalog, Nature genetics 2026, PMID:41419686. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
