Who was studied 1,458,999 European ancestry individuals, 240,296 African ancestry individuals, 58,370 mixed American ancestry individuals.
The effect
The reported allele is A; the catalogue records no effect size
; p = 4 × 10−14.
Where it sits Chromosome 6, band 6p22.1 — between genes, 16.2 kb from MCFD2P1.
What each result means
A/ATwo copies of the version the research linked to Substance use 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 Substance use disorder. That is a smaller link than two copies.
G/GNo copy of the version the research linked to Substance use disorder. This is the starting point the study compared everyone against.

Questions about rs34185469
What is rs34185469?
rs34185469 is a single position in the genome, in or near the near MCFD2P1 gene. Published research associates it with substance use 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 rs34185469 linked to?
On MyGeneLog this position is linked to Substance Use Disorder. The research behind each link, and its sources, are set out on that condition page.
Does having rs34185469 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 rs34185469 come from?
GWAS Catalog, Molecular psychiatry 2026, PMID:41057643. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
