The effect
Each copy of the G allele carried 1.09 times the odds of Crohn's disease (95% confidence interval 1.06-1.11); p = 3 × 10−11.
How common The G allele had a frequency of about 64% in the people studied.
Where it sits Chromosome 4, band 4p11 — in an intron of SLAIN2.
What each result means
A/ANo copy of the version the research linked to Crohn's disease. This is the starting point the study compared everyone against.
A/GOne copy of the version the research linked to Crohn's disease. That is a smaller link than two copies.
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.
rs7438704 is a single position in the genome, in or near the SLAIN2 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 rs7438704 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.
Does having rs7438704 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 rs7438704 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.
