Where it sits Chromosome 1, band 1p34.2 — in an intron of SZT2.
rs2842179 is a single position in the genome, in or near the SZT2 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.
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.
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.
