Who was studied 3,230 European ancestry cases, 4,829 European ancestry controls; replicated in 1,339 European ancestry trios, 2,325 European ancestry cases, 1,809 European ancestry controls.
The effect
Each copy of the G allele carried 1.35 times the odds of Crohn's disease; p = 5 × 10−17.
How common The G allele had a frequency of about 15% in the people studied.

What each result means
G/GTwo copies of the version the research linked to Crohn's disease. That is the strongest link of the three results. A link in a study is not a diagnosis.
G/TOne copy of the version the research linked to Crohn's disease. That is a smaller link than two copies.
T/TNo copy of the version the research linked to Crohn's disease. 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 rs2542151
What is rs2542151?
rs2542151 is a single position in the genome, in or near the PTPN2 gene. Published research associates it with crohn's disease. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs2542151 linked to?
On MyGeneLog this position is linked to Crohn's Disease. The research behind each link, and its sources, are set out on that condition page.
What do people read about alongside rs2542151?
Subjects that appear in the title or abstract of the same papers as this rsID include blood sugar and insulin (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 rs2542151 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 rs2542151 come from?
GWAS Catalog, Nat Genet 2008, PMID:18587394. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
