What the study found

Who was studied 449,734 European ancestry individuals; replicated in 248,098 European ancestry individuals.

The effect Each copy of the A allele shifted the measure 0.0203 higher (95% confidence interval 0.014-0.027); p = 2 × 10−10.

How common The A allele had a frequency of about 92% in the people studied.

Where it sits Chromosome 3, band 3q13.31 — in an intron of LSAMP.

What each result means

A/A Two copies of the version the research linked to Chronotype. That is the strongest link of the three results. A link in a study is not a diagnosis.
A/C One copy of the version the research linked to Chronotype. That is a smaller link than two copies.
C/C No copy of the version the research linked to Chronotype. This is the starting point the study compared everyone against.

Questions about rs79402305

What is rs79402305?

rs79402305 is a single position in the genome, in or near the LSAMP 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.

Does having rs79402305 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 rs79402305 come from?

GWAS Catalog, Nature communications 2019, PMID:30696823. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
