Who was studied 221,596 European ancestry cases, 1,564,466 European ancestry controls.
The effect
Each copy of the T allele shifted the measure 0.0254 lower (95% confidence interval 0.018-0.033); p = 8 × 10−11.
How common The T allele had a frequency of about 51% in the people studied.
Where it sits Chromosome 6, band 6p24.3 — in an intron of RREB1.
What each result means
C/CPublished research associates this genotype with typical/baseline likelihood of Hypothyroidism — no copies of the reported risk allele.
C/TPublished research associates this genotype (one copy of the reported risk allele) with an intermediate association with Hypothyroidism.
T/TPublished research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Hypothyroidism compared to the general population.

Questions about rs7451690
What is rs7451690?
rs7451690 is a single position in the genome, in or near the RREB1 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 rs7451690 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 rs7451690 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 rs7451690 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.
