Background: The common deletion of the glutathione S-transferase Mu 1 (GSTM1) gene in humans has been shown to be involved in xenobiotic metabolism and associated with bladder cancer. However, the evolution of this deletion has not been investigated. Results: In this study, we conducted comparative analyses of primate genomes. We demonstrated that the GSTM gene family has evolved through multiple structural variations, involving gene duplications, losses, large inversions and gene conversions. We further showed experimentally that the GSTM1 was polymorphically deleted in both humans and also in chimpanzees, through independent deletion events. To generalize our results, we searched for genic deletions that are polymorphic in both humans and chimpanzees. Consequently, we found only two such deletions among the thousands that we have searched, one of them being the GSTM1 deletion and the other surprisingly being another metabolizing gene, the UGT2B17. Conclusions: Overall, our results support the emerging notion that metabolizing gene families, such as the GSTM, NAT, UGT and CYP, have been evolving rapidly through gene duplication and deletion events in primates, leading to complex structural variation within and among species with unknown evolutionary consequences.
