Who was studied up to 9,585 European ancestry cases, up to 33,742 European ancestry controls.
The effect
Each copy of the A allele carried 1.27 times the odds of Rheumatoid arthritis (ACPA-positive) (95% confidence interval -); p = 1 × 10−12.
How common The A allele had a frequency of about 12% in the people studied.
Where it sits Chromosome X, band Xq28 — a synonymous change in TMEM187.
What each result means
A/ATwo copies of the version the research linked to Rheumatoid arthritis (ACPA-positive). 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 Rheumatoid arthritis (ACPA-positive). That is a smaller link than two copies.
G/GNo copy of the version the research linked to Rheumatoid arthritis (ACPA-positive). This is the starting point the study compared everyone against.

Questions about rs13397
What is rs13397?
rs13397 is a single position in the genome, in or near the IRAK1 gene. Published research associates it with rheumatoid arthritis (acpa-positive). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs13397 linked to?
On MyGeneLog this position is linked to Rheumatoid Arthritis. The research behind each link, and its sources, are set out on that condition page.
Does having rs13397 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 rs13397 come from?
GWAS Catalog, Nat Genet 2012, PMID:23143596. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
