Who was studied 1,822 Han Chinese ancestry cases, 4,650 Han Chinese ancestry controls, 20,352 European ancestry cases, 31,358 European ancestry controls.
The effect
Each copy of the A allele carried 1.07 times the odds of Bipolar disorder (95% confidence interval 1.045-1.091); p = 2 × 10−9.
Where it sits Chromosome 3, band 3q13.12 — in an intron of CD47.
What each result means
A/ATwo copies of the version the research linked to Bipolar disorder. 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 Bipolar disorder. That is a smaller link than two copies.
G/GNo copy of the version the research linked to Bipolar disorder. This is the starting point the study compared everyone against.
rs3804640 is a single position in the genome, in or near the CD47 gene. Published research associates it with bipolar disorder. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs3804640 linked to?
On MyGeneLog this position is linked to Bipolar Disorder. The research behind each link, and its sources, are set out on that condition page.
Does having rs3804640 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 rs3804640 come from?
GWAS Catalog, JAMA psychiatry 2021, PMID:33263727. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
