Who was studied 15,126 European ancestry cases, 95,725 European ancestry controls; replicated in 30,770 European ancestry cases, 286,913 European ancestry controls.
The effect
Each copy of the T allele carried 1.06 times the odds of Restless legs syndrome (95% confidence interval 1.04-1.08); p = 3 × 10−9.
How common The T allele had a frequency of about 20% in the people studied.
Where it sits Chromosome 13, band 13q21.33 — between genes, 179.9 kb from LOC124900345.
What each result means
G/GNo copy of the version the research linked to Restless legs syndrome. This is the starting point the study compared everyone against.
G/TOne copy of the version the research linked to Restless legs syndrome. That is a smaller link than two copies.
T/TTwo copies of the version the research linked to Restless legs syndrome. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs340561
What is rs340561?
rs340561 is a single position in the genome, in or near the DACH1 gene. Published research associates it with restless legs syndrome. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs340561 linked to?
On MyGeneLog this position is linked to Restless Legs Syndrome. The research behind each link, and its sources, are set out on that condition page.
Does having rs340561 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 rs340561 come from?
GWAS Catalog, Lancet Neurol 2017, PMID:29029846. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
