Where this position leads

What the study found

Who was studied 441,761 European ancestry individuals.

The effect Each copy of the G allele shifted the measure 0.0139 higher (95% confidence interval 0.0094-0.0184); p = 6 × 10⁻¹⁰.

Where it sits Chromosome 2, band 2q24.3 — in an intron of SCN2A.

What each result means

G/G 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.

G/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 with typical/baseline likelihood of Body mass index — no copies of the reported risk allele.

Questions about rs12477385

What is rs12477385?

rs12477385 is a single position in the genome, in or near the SCN2A 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 rs12477385 linked to?

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

Does having rs12477385 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 rs12477385 come from?

GWAS Catalog, Diabetologia 2023, PMID:37280435. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
