What the study found

Who was studied 257,365 African ancestry, admixed American, East Asian ancestry, European ancestry, South Asian ancestry, Greater Middle Eastern cases, 2,186,763 African ancestry, admixed American, East Asian ancestry, European ancestry, South Asian ancestry, Greater Middle Eastern controls.

The effect Each copy of the T allele shifted the measure 0.0222 lower (95% confidence interval 0.015-0.03); p = 9 × 10−9.

How common The T allele had a frequency of about 29% in the people studied.

Where it sits Chromosome 17, band 17p11.2 — between genes, 6.9 kb from MAP2K3.

What each result means

C/C Published research associates this genotype with typical/baseline likelihood of Hypothyroidism — no copies of the reported risk allele.
C/T Published research associates this genotype (one copy of the reported risk allele) with an intermediate association with Hypothyroidism.
T/T Published research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Hypothyroidism compared to the general population.

Questions about rs12939131

What is rs12939131?

rs12939131 is a single position in the genome, in or near the near MAP2K3 gene. Published research associates it with hypothyroidism. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs12939131 linked to?

On MyGeneLog this position is linked to Hypothyroidism. The research behind each link, and its sources, are set out on that condition page.

Does having rs12939131 mean I will get this?

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.

Where does the information about rs12939131 come from?

GWAS Catalog, Nature genetics 2026, PMID:41644669. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
