Who was studied 228,926 European ancestry cases, 1,611,415 European ancestry controls.
The effect
Each copy of the A allele shifted the measure 0.0421 lower (95% confidence interval 0.03-0.054); p = 2 × 10−11.
How common The A allele had a frequency of about 91% in the people studied.
Where it sits Chromosome 8, band 8q24.22 — between genes, 14.5 kb from MIR30B.
What each result means
A/ATwo copies of the version the research linked to Atrial fibrillation. That is the strongest link of the three results. A link in a study is not a diagnosis.
A/GOne copy of the version the research linked to Atrial fibrillation. That is a smaller link than two copies.
G/GNo copy of the version the research linked to Atrial fibrillation. This is the starting point the study compared everyone against.

Questions about rs72721963
What is rs72721963?
rs72721963 is a single position in the genome, in or near the near MIR30B gene. Published research associates it with atrial fibrillation. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs72721963 linked to?
On MyGeneLog this position is linked to Atrial Fibrillation. The research behind each link, and its sources, are set out on that condition page.
Does having rs72721963 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 rs72721963 come from?
GWAS Catalog, Nature communications 2025, PMID:40645996. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
