NUDT15 Mutation Analysis details

What NUDT15 Mutation Analysis shows

NUDT15 is a gene that makes an enzyme involved in breaking down the active forms of thiopurine medicines, such as azathioprine, mercaptopurine and thioguanine, which are used for some autoimmune conditions and blood cancers. This test looks for NUDT15 variants in DNA from your blood. The result is a lifelong genetic variant, not a level that changes. Variants that reduce enzyme function can lead to higher levels of active drug and a greater risk of side effects, particularly low blood counts. The result is used with TPMT testing and other information to predict your phenotype, and medicine decisions are made by your prescriber.
