Who was studied 452,633 European ancestry individuals; replicated in 541,333 European ancestry individuals.
The effect
Each copy of the C allele shifted the measure 0.0091 higher (95% confidence interval 0.0073-0.0109); p = 2 × 10−23.
Where it sits Chromosome 11, band 11q12.2 — in a non-coding transcript of FADS2.
What each result means
C/CTwo 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.
C/TOne copy of the version the research linked to Daytime nap. That is a smaller link than two copies.
T/TNo copy of the version the research linked to Daytime nap. This is the starting point the study compared everyone against.
Papers in Europe PMC whose title or abstract names both this rsID and that subject. A shared paper means somebody wrote about the two together — it is not a claim that this position explains the subject.
Questions about rs174541
What is rs174541?
rs174541 is a single position in the genome, in or near the FADS2 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 rs174541 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.
What do people read about alongside rs174541?
Subjects that appear in the title or abstract of the same papers as this rsID include heart and circulation (1 papers). A shared paper means somebody wrote about the two together; it is not a claim that this position explains the topic.
Does having rs174541 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 rs174541 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.
