Who was studied 342,566 European ancestry individuals.
The effect
Each copy of the G allele shifted the measure 0.0181 higher (95% confidence interval 0.013-0.024); p = 2 × 10−10.
Where it sits Chromosome 3, band 3q22.3 — in an intron of NCK1.
What each result means
A/ANo copy of the version the research linked to Body mass index. This is the starting point the study compared everyone against.
A/GOne copy of the version the research linked to Body mass index. That is a smaller link than two copies.
G/GTwo copies of the version the research linked to Body mass index. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs9840500
What is rs9840500?
rs9840500 is a single position in the genome, in or near the NCK1 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 rs9840500 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 rs9840500 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 rs9840500 come from?
GWAS Catalog, Scientific reports 2024, PMID:38538606. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
