ITPA is a gene. This site has 3 published variants inside it, each from a published genetic study, joining it to 2 condition pages and 1 drug page.
CPIC, the international group that writes gene-based prescribing guidelines, rates how strong the evidence is for each gene and medicine, from A (strong enough to change the prescription) to D (weak or conflicting). Every rating is shown, the weak ones included, so you can see where the evidence stops.

A gene page gathers published research; it is not a test result and not medical advice. If a gene matters to your health, talk to a doctor or a genetic counsellor.
