Where this position leads
What the study found
Who was studied 10,708 European ancestry individuals.
The effect Each copy of the T allele shifted the measure 0.411 higher (95% confidence interval 0.38-0.44); p = 2 × 10−200.
How common The T allele had a frequency of about 67% in the people studied.
Where it sits Chromosome 1, band 1q24.2 — in an intron of F5.
rs6701330 is a single position in the genome, in or near the F5 gene. Published research associates it with sulfotransferase family cytosolic 1b member 1 levels. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
F5 carries pharmacogenomic findings for Combined hormonal contraceptives. 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.
