Daytime sleepiness

SLC2A9 · rs543431433

Stands on its own. Nothing else here links to this position yet — but the page above is the point: what the research found, what each genotype means, and where it came from, in language you can read. Links to conditions, drugs and the senses appear automatically if we write them.

What the study found

Who was studied 112,717 European ancestry cases and controls.

The effect Each copy of the A allele shifted the measure 0.26 higher (95% confidence interval 0.17-0.35); p = 4 × 10⁻⁹.

How common The A allele had a frequency of about 0% in the people studied.

Where it sits Chromosome 4, band 4p16.1 — in an intron of SLC2A9.

What each result means

A/A Published research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Daytime sleepiness compared to the general population.

A/T Published research associates this genotype (one copy of the reported risk allele) with an intermediate association with Daytime sleepiness.

T/T Published research associates this genotype with typical/baseline likelihood of Daytime sleepiness — no copies of the reported risk allele.

Questions about rs543431433

What is rs543431433?

rs543431433 is a single position in the genome, in or near the SLC2A9 gene. Published research associates it with daytime sleepiness. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs543431433 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 rs543431433 come from?

GWAS Catalog, Nat Genet 2017, PMID:28604731. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
