GSTM1
GSTM1 encodes glutathione S-transferase mu 1, a phase II detoxification enzyme expressed mainly in the liver that conjugates glutathione to reactive electrophiles, carcinogens, and oxidative-stress byproducts to enable their elimination. The gene carries a very common copy-number deletion (null) polymorphism that abolishes enzyme activity entirely, which is the basis for the "detox enzyme" context tracked here and requires whole-genome copy-number/structural-variant reading rather than a single SNP call.
