ALDH1A2 · rs189452693
Where this position leads
Condition: Celiac Disease
What the study found
Who was studied 394,642 European ancestry individuals.
The effect Each copy of the C allele shifted the measure 0.0885 higher (95% confidence interval 0.063-0.114); p = 1 × 10−12.
How common The C allele had a frequency of about 1% in the people studied.
Where it sits Chromosome 15, band 15q21.3 — inside ALDH1A2.
rs189452693 is a single position in the genome, in or near the ALDH1A2 gene. Published research associates it with haematocrit percentage (ukb data field 30030). 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.
