Who was studied 452,633 European ancestry individuals; replicated in 541,333 European ancestry individuals.
The effect
Each copy of the G allele shifted the measure 0.0053 higher (95% confidence interval 0.0035-0.0071); p = 8 × 10−10.
Where it sits Chromosome 9, band 9p21.3 — in an intron of FOCAD.
What each result means
C/CNo copy of the version the research linked to Daytime nap. This is the starting point the study compared everyone against.
C/GOne copy of the version the research linked to Daytime nap. That is a smaller link than two copies.
G/GTwo copies of the version the research linked to Daytime nap. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs10811438
What is rs10811438?
rs10811438 is a single position in the genome, in or near the FOCAD gene. Published research associates it with daytime nap. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs10811438 linked to?
On MyGeneLog this position is linked to Sleep and Circadian Rhythm. The research behind each link, and its sources, are set out on that condition page.
Does having rs10811438 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 rs10811438 come from?
GWAS Catalog, Nat Commun 2021, PMID:33568662. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
