Splet21. mar. 2024 · TPMT (Thiopurine S-Methyltransferase) is a Protein Coding gene. Diseases associated with TPMT include Thiopurines, Poor Metabolism Of, 1 and Autoimmune Hepatitis.Among its related pathways are Metapathway biotransformation Phase I and II and Drug ADME.Gene Ontology (GO) annotations related to this gene include S … SpletSamples with a low Hb concentration were found to have significantly higher Hb-corrected TPMT activity than samples with a normal Hb concentration: 83 versus 44 nmol 6-methyl thioguanine /g Hb/h, P < 0.0001. These results strongly suggest that misleading high Hb-corrected TPMT activity is found in anaemic patients.
