Who was studied Up to 12,924 European ancestry cases, up to 21,442 European ancestry controls; replicated in Up to 25,683 European ancestry cases, up to 17,015 European ancestry controls.
The effect
Each copy of the C allele carried 1.15 times the odds of Crohn's disease (95% confidence interval 1.107-1.184); p = 5 × 10−28.
How common The C allele had a frequency of about 38% in the people studied.

What this is ClinVar's aggregate record for this position (as of its 2026-10-19 release), not a result about you. A classification describes the variant against the condition named, as laboratories submitted it. Whether a person carries this variant, and what that would mean for them, is a question for a clinical test and a genetic counsellor.
What each result means
C/CTwo 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.
C/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 rs9264942
What is rs9264942?
rs9264942 is a single position in the genome, in or near the PSORS1C1 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 rs9264942 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 rs9264942?
Subjects that appear in the title or abstract of the same papers as this rsID include infection and immunity (1 papers), natural selection (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 rs9264942 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 rs9264942 come from?
GWAS Catalog, Nature 2012, PMID:23128233. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
