Who was studied 6,968 European ancestry cases, 20,464 European ancestry controls; replicated in 10,679 European ancestry cases, 26,715 European ancestry controls, 397 Iranian ancestry cases, 342 Iranian ancestry controls, 1,239 Indian ancestry cases, 990 Indian ancestry controls, 1,134 East Asian ancestry cases, 3,719 East Asian ancestry controls.
The effect
Each copy of the A allele carried 1.09 times the odds of Ulcerative colitis; p = 3 × 10−10.
How common The A allele had a frequency of about 62% in the people studied.
Where it sits Chromosome 18, band 18q21.1 — between genes, 5.4 kb from CTIF.
What each result means
A/ATwo copies of the version the research linked to Ulcerative colitis. 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 Ulcerative colitis. That is a smaller link than two copies.
G/GNo copy of the version the research linked to Ulcerative colitis. This is the starting point the study compared everyone against.
rs7240004 is a single position in the genome, in or near the near CTIF gene. Published research associates it with ulcerative colitis. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs7240004 linked to?
On MyGeneLog this position is linked to Ulcerative Colitis. The research behind each link, and its sources, are set out on that condition page.
Does having rs7240004 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 rs7240004 come from?
GWAS Catalog, Nat Genet 2015, PMID:26192919. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
