Where this position leads
Condition: Peptic Ulcer Disease
What the study found
Who was studied 16,666 European ancestry cases, 439,661 European ancestry controls.
The effect The reported allele is C; the catalogue records no effect size ; p = 3 × 10−10.
How common The C allele had a frequency of about 56% in the people studied.
Where it sits Chromosome 17, band 17q21.2 — between genes, 1.3 kb from GAST.
rs34074411 is a single position in the genome, in or near the near GAST gene. Published research associates it with peptic ulcer disease. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
On MyGeneLog this position is linked to Peptic Ulcer Disease. The research behind each link, and its sources, are set out on that condition page.
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.
