Who was studied 394,642 European ancestry individuals.
The effect
Each copy of the A allele shifted the measure 0.0106 higher (95% confidence interval 0.0078-0.0134); p = 1 × 10−15.
How common The A allele had a frequency of about 54% in the people studied.
Where it sits Chromosome 5, band 5q31.1 — in an intron of PITX1-AS1.
What each result means
A/ATwo copies of the version the research linked to Impedance of arm left (UKB data field 23110). That is the strongest link of the three results. A link in a study is not a diagnosis.
A/GOne copy of the version the research linked to Impedance of arm left (UKB data field 23110). That is a smaller link than two copies.
G/GNo copy of the version the research linked to Impedance of arm left (UKB data field 23110). This is the starting point the study compared everyone against.

Questions about rs1650465
What is rs1650465?
rs1650465 is a single position in the genome, in or near the PITX1-AS1 gene. Published research associates it with impedance of arm left (ukb data field 23110). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs1650465 linked to?
On MyGeneLog this position is linked to Celiac Disease. The research behind each link, and its sources, are set out on that condition page.
Does having rs1650465 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 rs1650465 come from?
GWAS Catalog, Nature genetics 2025, PMID:39789286. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
