What the study found

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

The effect The reported allele is C; the catalogue records no effect size ; p = 6 × 10−20.

How common The C allele had a frequency of about 75% in the people studied.

Where it sits Chromosome 5, band 5q14.3 — in an intron of TMEM161B-DT.

What each result means

C/C 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.
C/T One copy of the version the research linked to Chronotype. That is a smaller link than two copies.
T/T No copy of the version the research linked to Chronotype. This is the starting point the study compared everyone against.

Questions about rs4269995

What is rs4269995?

rs4269995 is a single position in the genome, in or near the TMEM161B 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 rs4269995 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 rs4269995 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 rs4269995 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.
