Who was studied 6,171 Japanese ancestry cases, 27,178 Japanese ancestry controls; replicated in 5,336 Japanese ancestry cases, 11,726 Japanese ancestry controls.
The effect
The reported allele is G; the catalogue records no effect size
; p = 3 × 10−13.
Where it sits Chromosome 9, band 9q34.2 — in the 3′ untranslated region of ABO.
What each result means
A/APublished research associates this genotype with typical/baseline likelihood of Gastric cancer — no copies of the reported risk allele.
A/GPublished research associates this genotype (one copy of the reported risk allele) with an intermediate association with Gastric cancer.
G/GPublished research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Gastric cancer compared to the general population.

Questions about rs7849280
What is rs7849280?
rs7849280 is a single position in the genome, in or near the ABO gene. Published research associates it with gastric 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 rs7849280 linked to?
On MyGeneLog this position is linked to Non-Cardia Gastric Cancer. The research behind each link, and its sources, are set out on that condition page.
Does having rs7849280 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 rs7849280 come from?
GWAS Catalog, Cancer Sci 2018, PMID:30281874. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
