Who was studied 1,115 Han Chinese ancestry cases, 10,154 Han Chinese ancestry controls.
The effect
Each copy of the T allele carried 3.42 times the odds of IgG4-related disease (95% confidence interval 3.03-3.87); p = 2 × 10−85.
Where it sits Chromosome 7, band 7p22.1 — between genes, 7 kb from EVA1CP3.
What each result means
A/ANo copy of the version the research linked to IgG4-related disease. This is the starting point the study compared everyone against.
A/TOne copy of the version the research linked to IgG4-related disease. That is a smaller link than two copies.
T/TTwo copies of the version the research linked to IgG4-related disease. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs7802039
What is rs7802039?
rs7802039 is a single position in the genome, in or near the near CCZ1B gene. Published research associates it with igg4-related 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 rs7802039 linked to?
On MyGeneLog this position is linked to IgG4-Related Disease. The research behind each link, and its sources, are set out on that condition page.
Does having rs7802039 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 rs7802039 come from?
GWAS Catalog, Annals of the rheumatic diseases 2026, PMID:41298177. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
