Who was studied 1,122,049 European ancestry individuals.
The effect
Each copy of the G allele shifted the measure 0.0122 lower (95% confidence interval 0.0093-0.0151); p = 2 × 10−16.
Where it sits Chromosome 6, band 6p21.1 — between genes, 2.9 kb from TREM2.
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 rs7748777
What is rs7748777?
rs7748777 is a single position in the genome, in or near the near TREM2 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 rs7748777 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 rs7748777 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 rs7748777 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.
