Who was studied 113,054 European ancestry cases and controls.
The effect
Each copy of the T allele shifted the measure 0.32 higher (95% confidence interval 0.21-0.43); p = 6 × 10−9.
How common The T allele had a frequency of about 0% in the people studied.
Where it sits Chromosome 5, band 5q12.3 — in an intron of NLN.
What each result means
C/CPublished research associates this genotype with typical/baseline likelihood of Daytime nap — 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 Daytime nap.
T/TPublished research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Daytime nap compared to the general population.

Questions about rs755927998
What is rs755927998?
rs755927998 is a single position in the genome, in or near the NLN 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 rs755927998 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 rs755927998 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 rs755927998 come from?
GWAS Catalog, Nat Genet 2017, PMID:28604731. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
