What the study found

Who was studied 394,642 European ancestry individuals.

The effect Each copy of the A allele shifted the measure 0.0943 lower (95% confidence interval 0.08-0.108); p = 3 × 10−45.

How common The A allele had a frequency of about 2% in the people studied.

Where it sits Chromosome 18, band 18q21.32 — between genes, 4.5 kb from MC4R.

What each result means

A/A Two copies of the version the research linked to Trunk fat mass (UKB data field 23128). That is the strongest link of the three results. A link in a study is not a diagnosis.
A/T One copy of the version the research linked to Trunk fat mass (UKB data field 23128). That is a smaller link than two copies.
T/T No copy of the version the research linked to Trunk fat mass (UKB data field 23128). This is the starting point the study compared everyone against.

Questions about rs79566431

What is rs79566431?

rs79566431 is a single position in the genome, in or near the near MC4R gene. Published research associates it with trunk fat mass (ukb data field 23128). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs79566431 linked to?

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

Does having rs79566431 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 rs79566431 come from?

GWAS Catalog, Nature genetics 2025, PMID:39789286. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
