Condition: Varicose Veins
What the study found
Who was studied 9,577 British ancestry cases, 327,959 British ancestry controls.
The effect Each copy of the T allele shifted the measure 0.263 lower (95% confidence interval 0.23-0.29); p = 4 × 10−65.
How common The T allele had a frequency of about 69% in the people studied.
Where it sits Chromosome 1, band 1p36.22 — in an intron of CASZ1.

What this is ClinVar's aggregate record for this position (as of its 2026-09-24 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.
rs11121615 is a single position in the genome, in or near the CASZ1 gene. Published research associates it with varicose veins. 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 Varicose Veins. 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.
