Thyroid stimulating hormone levels

near HLA-C · rs2524118

Where this position leads

Condition: Thyroid Stimulating Hormone (TSH) Levels

What the study found

Who was studied 482,873 European ancestry individuals.

The effect Each copy of the A allele shifted the measure 0.063 higher (95% confidence interval 0.057-0.069); p = 1 × 10⁻⁷⁸.

How common The A allele had a frequency of about 12% in the people studied.

Where it sits Chromosome 6, band 6p21.33 — between genes, 5.9 kb from HLA-C.

What each result means

A/A Published research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Thyroid stimulating hormone levels compared to the general population.

A/T Published research associates this genotype (one copy of the reported risk allele) with an intermediate association with Thyroid stimulating hormone levels.

T/T Published research associates this genotype with typical/baseline likelihood of Thyroid stimulating hormone levels — no copies of the reported risk allele.

Questions about rs2524118

What is rs2524118?

rs2524118 is a single position in the genome, in or near the near HLA-C gene. Published research associates it with thyroid stimulating hormone levels. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs2524118 linked to?

On MyGeneLog this position is linked to Thyroid Stimulating Hormone (TSH) Levels. The research behind each link, and its sources, are set out on that condition page.

Does having rs2524118 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 rs2524118 come from?

GWAS Catalog, Nature genetics 2025, PMID:41238958. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
