Who was studied 981 European ancestry cases, 1,002 European ancestry controls; replicated in 10,287 European ancestry cases, 10,401 European ancestry controls, 4,400 Japanese ancestry cases, 3,179 Japanese ancestry controls, 1,789 cases, 1,771 controls.
The effect
Each copy of the C allele carried 1.11 times the odds of Colorectal cancer (95% confidence interval 1.08-1.15); p = 6 × 10−10.
How common The C allele had a frequency of about 43% in the people studied.
Where it sits Chromosome 11, band 11q23.1 — in an intron of POU2AF3.
What each result means
A/ANo copy of the version the research linked to Colorectal cancer. This is the starting point the study compared everyone against.
A/COne copy of the version the research linked to Colorectal cancer. That is a smaller link than two copies.
C/CTwo copies of the version the research linked to Colorectal cancer. That is the strongest link of the three results. A link in a study is not a diagnosis.
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 rs3802842
What is rs3802842?
rs3802842 is a single position in the genome, in or near the POU2AF3 gene. Published research associates it with colorectal cancer. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs3802842 linked to?
On MyGeneLog this position is linked to Colorectal Cancer. The research behind each link, and its sources, are set out on that condition page.
What do people read about alongside rs3802842?
Subjects that appear in the title or abstract of the same papers as this rsID include blood sugar and insulin (2 papers). A shared paper means somebody wrote about the two together; it is not a claim that this position explains the topic.
Does having rs3802842 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 rs3802842 come from?
GWAS Catalog, Nat Genet 2008, PMID:18372901. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
