Who was studied 182,798 British ancestry individuals.
The effect
Each copy of the T allele shifted the measure 0.0363 higher; p = 2 × 10−13.
How common The T allele had a frequency of about 12% in the people studied.
Where it sits Chromosome 6, band 6p22.1 — in an intron of HCG15.
What each result means
G/GNo copy of the version the research linked to Fluid intelligence. This is the starting point the study compared everyone against.
G/TOne copy of the version the research linked to Fluid intelligence. That is a smaller link than two copies.
T/TTwo copies of the version the research linked to Fluid intelligence. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs3129794
What is rs3129794?
rs3129794 is a single position in the genome, in or near the HCG15 gene. Published research associates it with fluid intelligence. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs3129794 linked to?
On MyGeneLog this position is linked to Intelligence. The research behind each link, and its sources, are set out on that condition page.
Does having rs3129794 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 rs3129794 come from?
GWAS Catalog, Communications biology 2026, PMID:42092107. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
