Who was studied 628 European ancestry cases, 1,644 European ancestry controls; replicated in 1,550 European ancestry cases, 2,269 European ancestry controls, 285 French Canadian founder cases, 842 French Canadian founder controls.
The effect
Each copy of the A allele carried 1.44 times the odds of Restless legs syndrome (95% confidence interval 1.31-1.59); p = 6 × 10−10.
How common The A allele had a frequency of about 12% in the people studied.
Where it sits Chromosome 9, band 9p23 — in an intron of PTPRD.
What each result means
A/ATwo 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.
A/GOne copy of the version the research linked to Restless legs syndrome. That is a smaller link than two copies.
G/GNo copy of the version the research linked to Restless legs syndrome. This is the starting point the study compared everyone against.
rs4626664 is a single position in the genome, in or near the PTPRD 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 rs4626664 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 rs4626664 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 rs4626664 come from?
GWAS Catalog, Nat Genet 2008, PMID:18660810. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
