What the study found

Who was studied 593,724 European ancestry cases, 1,771,286 European ancestry controls.

The effect Each copy of the A allele shifted the measure 0.017 higher (95% confidence interval 0.013-0.021); p = 1 × 10−11.

Where it sits Chromosome 7, band 7q31.31 — in an intron of KCND2.

What each result means

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

What conditions is rs62472321 linked to?

On MyGeneLog this position is linked to Insomnia. The research behind each link, and its sources, are set out on that condition page.

Does having rs62472321 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 rs62472321 come from?

GWAS Catalog, Nature genetics 2022, PMID:35835914. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
