Condition: Medication Use as a Genetic Trait
What the study found
Who was studied 31,904 European ancestry cases, 172,474 European ancestry controls.
The effect Each copy of the C allele shifted the measure 0.0671 lower (95% confidence interval 0.045-0.089); p = 3 × 10−9.
How common The C allele had a frequency of about 15% in the people studied.
Where it sits Chromosome 5, band 5q15 — in an intron of ERAP1.
rs27041 is a single position in the genome, in or near the ERAP1 gene. Published research associates it with medication use (calcium channel blockers). 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 Medication Use as a Genetic Trait. 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.
