ALDH3A1 · rs4646789
Where this position leads
Condition: Celiac Disease
What the study found
Who was studied 47,745 European ancestry individuals.
The effect Each copy of the C allele shifted the measure 0.351 higher (95% confidence interval 0.29-0.41); p = 2 × 10−38.
How common The C allele had a frequency of about 1% in the people studied.
Where it sits Chromosome 17, band 17p11.2 — in the 5′ untranslated region of ALDH3A1.
rs4646789 is a single position in the genome, in or near the ALDH3A1 gene. Published research associates it with aldh3a1 protein levels. 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 Celiac 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.
