Where this position leads
Condition: Celiac Disease
What the study found
Who was studied 47,745 European ancestry individuals.
The effect Each copy of the T allele shifted the measure 0.0251 lower (95% confidence interval 0.017-0.034); p = 1 × 10−20.
How common The T allele had a frequency of about 16% in the people studied.
Where it sits Chromosome 16, band 16p12.3 — in an intron of UMOD.

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.
rs12934455 is a single position in the genome, in or near the UMOD gene. Published research associates it with btn2a1 protein levels. 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 Celiac Disease. 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.
