Where this position leads
What the study found
Who was studied 5,347 Icelandic ancestry individuals.
The effect Each copy of the G allele shifted the measure 0.385 lower (95% confidence interval 0.28-0.49); p = 3 × 10−13.
How common The G allele had a frequency of about 3% in the people studied.
Where it sits Chromosome 1, band 1q24.2 — in the 3′ untranslated region of F5.

What this is ClinVar's aggregate record for this position (as of its 2026-10-19 release), not a result about you. A classification describes the variant against the condition named, as laboratories submitted it. Whether a person carries this variant, and what that would mean for them, is a question for a clinical test and a genetic counsellor.
rs72708013 is a single position in the genome, in or near the F5 gene. Published research associates it with serum levels of protein surf1. 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.
