SLC6A9 · rs113551349
Where this position leads
What the study found
Who was studied 18,345 European ancestry ADHD cases, 14,374 European ancestry cannabis use cases, 50,410 European ancestry controls.
The effect Each copy of the C allele carried 1.10 times the odds of Attention deficit hyperactivity disorder or cannabis use (95% confidence interval 1.08-1.14); p = 5 × 10−10.
Where it sits Chromosome 1, band 1p34.1 — in an intron of SLC6A9.
rs113551349 is a single position in the genome, in or near the SLC6A9 gene. Published research associates it with attention deficit hyperactivity disorder or cannabis use. 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 ADHD (Attention Deficit Hyperactivity 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.
