Where this position leads
Condition: Major Depressive Disorder
What the study found
Who was studied 6,997 European ancestry female cases, 16,172 European ancestry female controls, 3,852 European ancestry male cases, 16,034 European ancestry male controls.
The effect Each copy of the A allele shifted the measure 0.29 higher (95% confidence interval 0.19-0.39); p = 2 × 10−8.
How common The A allele had a frequency of about 8% in the people studied.
Where it sits Chromosome 3, band 3p22.3 — in an intron of CRTAP.
rs4478037 is a single position in the genome, in or near the CRTAP gene. Published research associates it with major depressive disorder. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
On MyGeneLog this position is linked to Major Depressive Disorder. The research behind each link, and its sources, are set out on that condition page.
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.
