Who was studied 342,566 European ancestry individuals.
The effect
Each copy of the T allele shifted the measure 0.0253 higher (95% confidence interval 0.02-0.03); p = 4 × 10−23.
Where it sits Chromosome 1, band 1q32.1 — in an intron of IPO9-AS1.
What each result means
C/CNo copy of the version the research linked to Body mass index. This is the starting point the study compared everyone against.
C/TOne copy of the version the research linked to Body mass index. That is a smaller link than two copies.
T/TTwo 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 rs2644109
What is rs2644109?
rs2644109 is a single position in the genome, in or near the IPO9-AS1 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 rs2644109 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 rs2644109 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 rs2644109 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.
