C/CPublished research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Chronotype compared to the general population.
C/TPublished research associates this genotype (one copy of the reported risk allele) with an intermediate association with Chronotype.
T/TPublished research associates this genotype with typical/baseline likelihood of Chronotype — no copies of the reported risk allele.

Questions about rs77641763
What is rs77641763?
rs77641763 is a single position in the genome, in or near the EXD3 gene. Published research associates it with chronotype. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs77641763 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 rs77641763 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 rs77641763 come from?
GWAS Catalog, PLoS Genet 2016, PMID:27494321. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
