Condition: Medication Use as a Genetic Trait
What the study found
Who was studied 31,700 European ancestry cases, 192,324 European ancestry controls.
The effect Each copy of the G allele shifted the measure 0.0573 higher (95% confidence interval 0.041-0.074); p = 2 × 10−11.
How common The G allele had a frequency of about 39% in the people studied.
Where it sits Chromosome 5, band 5q23.3 — in an intron of FBN2.

What this is ClinVar's aggregate record for this position (as of its 2026-09-24 release), not a result about you. A classification describes the variant against the condition named, as laboratories submitted it. Whether a person carries this variant, and what that would mean for them, is a question for a clinical test and a genetic counsellor.
rs17677603 is a single position in the genome, in or near the FBN2 gene. Published research associates it with medication use (beta blocking agents). 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.
