Drug response
What is rs2235015?
rs2235015 is a single-nucleotide polymorphism (SNP) in the ABCB1 gene (ATP-binding cassette subfamily B member 1 (P-glycoprotein)). Each person carries two copies, one from each parent, so a result is reported as a pair of letters such as CT. The table below describes what studies associate with each genotype; the association is statistical, across populations, and is not a diagnosis.

Is rs2235015 on 23andMe and AncestryDNA chips?
Chip coverage is not recorded for this variant. Orviva reports it when a raw-data file contains it directly or via a well-correlated proxy SNP, and says so when it does not.

Genetic associations describe risk across populations, not a diagnosis for any one person. Most variants shift risk modestly and act alongside lifestyle, environment and other genes. Consumer DNA chips do not read every position and can be wrong at any single one. For general education only; talk to a clinician or genetic counsellor before acting on anything here, and never change a prescribed medicine without your prescriber.
