The discovery and implementation of thiopurine methyltransferase (TPMT) pharmacogenetics has been a success story and has reduced the suffering from serious adverse reactions during thiopurine treatment of childhood leukaemia and inflammatory bowel disease. This MiniReview summarizes four studies included in Dr Zimdahl Kahlin's doctoral thesis as well as the current knowledge on this field of research. The genotype-phenotype concordance of TPMT in a cohort of 12 663 individuals with clinically analysed TPMT status is described.

Transcription factor c-MYC is a potent oncoprotein; however, the mechanism of transcriptional regulation via MYC-protein interactions remains poorly understood. The TATA-binding protein (TBP) is an essential component of the transcription initiation complex TFIID and is required for gene expression. We identify two discrete regions mediating MYC-TBP interactions using structural, biochemical and cellular approaches.
