Who was studied 360,388 European ancestry individuals, 165,056 East Asian ancestry individuals.
The effect
Each copy of the T allele shifted the measure 0.0124 lower (95% confidence interval 0.0099-0.0149); p = 2 × 10−21.
Where it sits Chromosome 6, band 6q27 — in an intron of PDE10A.
What each result means
C/CPublished research associates this genotype with typical/baseline likelihood of Height — no copies of the reported risk allele.
C/TPublished research associates this genotype (one copy of the reported risk allele) with an intermediate association with Height.
T/TPublished research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Height compared to the general population.
rs991946 is a single position in the genome, in or near the PDE10A gene. Published research associates it with height. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs991946 linked to?
On MyGeneLog this position is linked to Height. The research behind each link, and its sources, are set out on that condition page.
Does having rs991946 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 rs991946 come from?
GWAS Catalog, Nature genetics 2021, PMID:34594039. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
