Where this position leads

Conditions: Childhood Body Mass Index, Obesity and Body Weight

What the study found

Who was studied 507,850 East Asian ancestry individuals, 420,829 European ancestry individuals.

The effect Each copy of the T allele shifted the measure 0.0175 lower (95% confidence interval 0.014-0.021); p = 1 × 10⁻²⁸.

Where it sits Chromosome 6, band 6p21.2 — in an intron of LRFN2.

What each result means

C/C Published research associates this genotype with typical/baseline likelihood of Body mass index — 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 Body mass index.

T/T Published research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Body mass index compared to the general population.

Questions about rs9471333

What is rs9471333?

rs9471333 is a single position in the genome, in or near the LRFN2 gene. Published research associates it with body mass index. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs9471333 linked to?

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

Does having rs9471333 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 rs9471333 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.
