The enzyme, present in human red blood cells. ( RBC) Sunquest Code: TPMT. Epic Code: LAB6987, Epic Name: Thiopurine Methyltransferase, RBC. Synonyms: Thiopurine Methyltransferase (TPMT) Enzyme Activity Thiopurine methyltransferase or thiopurine S-methyltransferase (TPMT) is an enzyme that in humans is encoded by the TPMT gene. A pseudogene for this locus To evaluate this assay, we compared it with conventional TPMT phenotyping, which uses a red blood cell (RBC) lysate and genotyping for analysis of common Distinct inheritable differences in levels of red blood cell TPMT have been detected among patients.
