Clinical Pharmacogenetics Implementation Consortium (CPIC) Guideline for Thiopurine Dosing Based on TPMT and NUDT15 Genotypes: 2025 Update. [PDF]
Thiopurine methyltransferase (TPMT) and Nudix hydrolase 15 (NUDT15) are key enzymes that catabolize thiopurines. Decreased or no‐function alleles in TPMT and NUDT15 are associated with reduced or no enzyme activity and predictive of pronounced adverse effects, including severe myelosuppression, that may occur among individuals treated with standard ...

Clinical and Economic Impact of Expanded TPMT Testing to Prevent Thiopurine-Induced Myelosuppression in Australia: A Budget Impact Analysis. [PDF]
ABSTRACT Testing thiopurine methyltransferase (TPMT) enzyme activity or genotype prior to thiopurine prescribing is recommended to reduce the risk of moderate to severe—and potentially fatal—myelosuppression in poor or intermediate TPMT metabolizers. Despite this, only about one‐third of individuals prescribed thiopurines in Australia currently receive

Genetic Determinants of Hematopoietic Toxicity Risk in Thai Pediatric Patients Undergoing 6-Mercaptopurine Treatment. [PDF]
ABSTRACT The nucleoside diphosphate‐linked moiety X‐type motif 15 (NUDT15) has been identified as a key genetic determinant of 6‐mercaptopurine (6‐MP)‐induced hematopoietic toxicity in populations with a high frequency of NUDT15 variants but a low frequency of thiopurine S‐methyltransferase (TPMT) variants.

Unraveling Novel Genetic Determinants of Thiopurine Response Via TWAS. [PDF]
Acute lymphoblastic leukemia (ALL) is the most common childhood cancer. Thiopurines such as 6‐mercaptopurine (6MP) are essential in ALL maintenance therapy. However, dose‐limiting toxicities can significantly disrupt treatment. While genetic variants in TPMT and NUDT15 are known to affect thiopurine response, many patients with normal function ...

6-thioguanine treatment in inflammatory bowel disease: A critical appraisal by a European 6-TG working party [PDF]
Recently, the suggestion to use 6-thioguanine (6-TG) as an alternative thiopurine in patients with inflammatory bowel disease (IBD) has been discarded due to reports about possible (hepato) toxicity. During meetings arranged in Vienna and Prague in 2004,

Background: Thiopurine methyltransferase (TPMT) plays a significant role in the metabolism of thiopurines, and, for patients with inflammatory bowel disease (IBD), it is useful to perform TPMT genotyping prior to azathioprine (AZA) treatment.

Association between Thiopurine S-Methyltransferase Polymorphisms and Azathioprine-Induced Adverse Drug Reactions in Patients with Autoimmune Diseases: A Meta-Analysis. [PDF]
Azathioprine (AZA) is widely used as an immunosuppressive drug in autoimmune diseases, but its use is limited by significant adverse drug reactions (ADRs). Thiopurine S-methyltransferase (TPMT) is an important enzyme involved in AZA metabolism.
