One amino acid makes a difference–Characterization of a new TPMT allele and the influence of SAM on TPMT stability [PDF]
AbstractThiopurine induced toxicity is associated with defects in the thiopurine methyltransferase (TPMT) gene. TPMT is a polymorphic enzyme, with most of the single nucleotide polymorphisms (SNPs) causing an amino acid change, altering the enzymatic activity of the TPMT protein.

Reactive sulfur species are inactivated and excreted as trimethylsulfonium ion by thiopurine S-methyltransferase [PDF]
Reactive sulfur species (RSS) play essential roles in cellular signaling, redox regulation, and defense against electrophilic stress. However, excessive RSS are cytotoxic and must be strictly regulated.

Common Polymorphism’s Analysis of Thiopurine S-Methyltransferase (TPMT) in Iranian Population [PDF]
Objective: Thiopurine S-methyltransferase (TPMT) catalyses the S-methylation of thiopurinedrugs. Low activity phenotypes are correlated with several mutations in the TPMTgene and adverse drug reactions.

Polymorphic Variation in TPMT Is the Principal Determinant of TPMT Phenotype: A Meta‐Analysis of Three Genome‐Wide Association Studies [PDF]
Thiopurine‐related hematotoxicity in pediatric acute lymphoblastic leukemia (ALL) and inflammatory bowel diseases has been linked to genetically defined variability in thiopurine S‐methyltransferase (TPMT) activity. While gene testing of TPMT is being clinically implemented, it is unclear if additional genetic variation influences TPMT activity with ...

Liver Injury From Medications Used for Treating Inflammatory Bowel Disease: The Drug-Induced Liver Injury Network Experience. [PDF]
ABSTRACT Background We aimed to investigate and characterise DILI due to approved therapies for inflammatory bowel disease (IBD). Methods Using the Drug‐Induced Liver Injury Network (DILIN) prospective study, we evaluated definite, highly likely, or probable DILI attributed to IBD therapies, including use for non‐IBD indications (but excluding ...

Higher prevalence of NUDT15 rs116855232 compared to TPMT rs1142345 in a Chinese cohort and its implications for thiopurine therapy [PDF]
BackgroundThiopurine drugs are widely used as immunosuppressants and chemotherapeutic agents in clinical practice, but their adverse effects significantly limit their clinical application. TPMT c.719A>G (rs1142345) and NUDT15 c.415C>T (rs116855232)
