From: Complex evolution of the GSTM gene family involves sharing of GSTM1 deletion polymorphism in humans and chimpanzees

An evolutionary model of the GSTM1 deletion in humans and chimpanzees. Based on our results, we built a model to describe the mutational events through evolutionary time: (a) Gene conversions occurred between SD1 and SD2 before the divergence of humans and chimpanzees. (b) The GSTM1 gene was deleted in both human and chimpanzee lineages with very similar breakpoints. (c) A chimpanzee-specific sequence exchange between the SD1 and SD2 occurred
