What the study found

Who was studied 153,950 Korean ancestry individuals.

The effect Each copy of the A allele shifted the measure 0.0443 lower (95% confidence interval 0.033-0.055); p = 5 × 10−15.

How common The A allele had a frequency of about 7% in the people studied.

Where it sits Chromosome 15, band 15q26.3 — in an intron of IRAIN.

What each result means

A/A Two copies of the version the research linked to Weight. That is the strongest link of the three results. A link in a study is not a diagnosis.
A/G One copy of the version the research linked to Weight. That is a smaller link than two copies.
G/G No copy of the version the research linked to Weight. This is the starting point the study compared everyone against.

Questions about rs143251811

What is rs143251811?

rs143251811 is a single position in the genome, in or near the IRAIN gene. Published research associates it with weight. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs143251811 linked to?

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

Does having rs143251811 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 rs143251811 come from?

GWAS Catalog, Nature communications 2025, PMID:40436827. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
