Who was studied 1,122,049 European ancestry individuals.
The effect
Each copy of the G allele shifted the measure 0.0119 higher (95% confidence interval 0.0088-0.015); p = 3 × 10−13.
Where it sits Chromosome 4, band 4q31.1 — in an intron of MAML3.
What each result means
A/APublished research associates this genotype with typical/baseline likelihood of Body mass index — no copies of the reported risk allele.
A/GPublished research associates this genotype (one copy of the reported risk allele) with an intermediate association with Body mass index.
G/GPublished 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 rs13109980
What is rs13109980?
rs13109980 is a single position in the genome, in or near the MAML3 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 rs13109980 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 rs13109980 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 rs13109980 come from?
GWAS Catalog, Nature communications 2022, PMID:36581621. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
