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 90,515 individuals.
The effect
Each copy of the C allele shifted the measure 0.521 higher (95% confidence interval 0.36-0.69); p = 4 × 10−10.
Where it sits Chromosome 3, band 3p25.1 — in an intron of C3orf20.
What each result means
A/ANo copy of the version the research linked to Sleep (1/3-day periodicity). This is the starting point the study compared everyone against.
A/COne copy of the version the research linked to Sleep (1/3-day periodicity). That is a smaller link than two copies.
C/CTwo copies of the version the research linked to Sleep (1/3-day periodicity). That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs76226780
What is rs76226780?
rs76226780 is a single position in the genome, in or near the C3orf20 gene. Published research associates it with sleep (1/3-day periodicity). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs76226780 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 rs76226780 come from?
GWAS Catalog, PLoS genetics 2020, PMID:33075057. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
