Where this position leads
Drug: Metformin
What the study found
Who was studied 239,268 European ancestry individuals.

Where it sits Chromosome 3, band 3q26.2 — in an intron of SLC2A2.
rs7643425 is a single position in the genome, in or near the SLC2A2 gene. Published research associates it with omega-3 fatty acid levels. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
SLC2A2 carries pharmacogenomic findings for Metformin. That is educational information, not a prescription or a dosing guide. Any decision to start, stop or change a medicine belongs with the clinician or pharmacist managing your treatment.
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.
