Who was studied 60,620 European ancestry cases, 970,216 European ancestry controls.
The effect
Each copy of the C allele carried 1.07 times the odds of Atrial fibrillation (95% confidence interval 1.04-1.09); p = 2 × 10−8.
How common The C allele had a frequency of about 8% in the people studied.
Where it sits Chromosome 18, band 18q21.2 — between genes, 5 kb from SRSF10P1.
What each result means
C/CTwo 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.
C/TOne copy of the version the research linked to Atrial fibrillation. That is a smaller link than two copies.
T/TNo copy of the version the research linked to Atrial fibrillation. This is the starting point the study compared everyone against.
rs9963878 is a single position in the genome, in or near the MEX3C 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 rs9963878 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 rs9963878 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 rs9963878 come from?
GWAS Catalog, Nat Genet 2018, PMID:30061737. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
