Morning vs. evening chronotype

VIP · rs9479402

Where this position leads

What the study found

Who was studied 38,937 European ancestry morning chronotype individuals, 50,346 European ancestry evening chronotype individuals.

The effect Each copy of the C allele carried 1.45 times the odds of Morning vs. evening chronotype (95% confidence interval -); p = 4 × 10⁻¹¹.

How common The C allele had a frequency of about 1% in the people studied.

Where it sits Chromosome 6, band 6q25.2 — in an intron of LINC02840.

What each result means

C/C Two copies of the version the research linked to Morning vs. evening 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 Morning vs. evening chronotype. That is a smaller link than two copies.

T/T No copy of the version the research linked to Morning vs. evening chronotype. This is the starting point the study compared everyone against.

Questions about rs9479402

What is rs9479402?

rs9479402 is a single position in the genome, in or near the VIP gene. Published research associates it with morning vs. evening 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 rs9479402 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.

What do people read about alongside rs9479402?

Subjects that appear in the title or abstract of the same papers as this rsID include sleep and insomnia (1 papers). A shared paper means somebody wrote about the two together; it is not a claim that this position explains the topic.

Does having rs9479402 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 rs9479402 come from?

GWAS Catalog, Nat Commun 2016, PMID:26835600. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
