Aortic stenosis

COL4A2 · rs3803236

Where this position leads

What the study found

Who was studied 80,823 European ancestry cases, 2,383,572 European ancestry controls.

The effect Each copy of the C allele carried 1.03 times the odds of Aortic stenosis (95% confidence interval 1.02-1.04); p = 4 × 10⁻⁸.

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

Where it sits Chromosome 13, band 13q34 — at a splice region of COL4A2.

What each result means

C/C 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.

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

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

Questions about rs3803236

What is rs3803236?

rs3803236 is a single position in the genome, in or near the COL4A2 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 rs3803236 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 rs3803236 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 rs3803236 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.
