Who was studied 306 European ancestry cases, 15,664 European ancestry controls; replicated in 311 European ancestry cases, 1,895 European ancestry controls.
The effect
Each copy of the A allele carried 1.90 times the odds of Restless legs syndrome (95% confidence interval 1.50-2.20); p = 1 × 10−17.
How common The A allele had a frequency of about 66% in the people studied.
Where it sits Chromosome 6, band 6p21.2 — in an intron of BTBD9.
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.
Papers in Europe PMC whose title or abstract names both this rsID and that subject. A shared paper means somebody wrote about the two together — it is not a claim that this position explains the subject.
Questions about rs3923809
What is rs3923809?
rs3923809 is a single position in the genome, in or near the BTBD9 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 rs3923809 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.
What do people read about alongside rs3923809?
Subjects that appear in the title or abstract of the same papers as this rsID include sleep and insomnia (1 papers), adhd and attention (1 papers), kidneys (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 rs3923809 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 rs3923809 come from?
GWAS Catalog, N Engl J Med 2007, PMID:17634447. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
