Stands on its own.
Nothing else here links to this position yet — but the page above is the point: what the
research found, what each genotype means, and where it came from, in language you can
read. Links to conditions, drugs and the senses appear automatically if we write them.
What the study found
Who was studied 84,810 European ancestry individuals; replicated in 4,401 European ancestry individuals.
The effect
Each copy of the G allele shifted the measure 0.052 higher (95% confidence interval 0.038-0.066); p = 6 × 10−14.
How common The G allele had a frequency of about 87% in the people studied.
Where it sits Chromosome 16, band 16p12.3 — between genes, 12.2 kb from SNRPEP3.
What each result means
G/GTwo copies of the version the research linked to Sleep (number of episodes). That is the strongest link of the three results. A link in a study is not a diagnosis.
G/TOne copy of the version the research linked to Sleep (number of episodes). That is a smaller link than two copies.
T/TNo copy of the version the research linked to Sleep (number of episodes). This is the starting point the study compared everyone against.

Questions about rs8045740
What is rs8045740?
rs8045740 is a single position in the genome, in or near the GPR139 gene. Published research associates it with sleep (number of episodes). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs8045740 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 rs8045740 come from?
GWAS Catalog, Nature communications 2019, PMID:30952852. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
