Where this position leads
Condition: Venous Thromboembolism
What the study found
Who was studied 23,151 European ancestry cases, 553,439 European ancestry controls, 2,261 African American cases, 49,400 African American controls, 654 Hispanic cases, 21,214 Hispanic controls; replicated in 17,672 cases, 167,295 controls.
The effect Each copy of the A allele carried 1.07 times the odds of Venous thromboembolism (95% confidence interval 1.05-1.09); p = 3 × 10−17.
How common The A allele had a frequency of about 72% in the people studied.
Where it sits Chromosome X, band Xq27.1 — a missense change in F9.

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.
rs6048 is a single position in the genome, in or near the F9 gene. Published research associates it with venous thromboembolism. 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 Venous Thromboembolism. 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.
