We assessed whether, in a Caucasian population, low or null activity polymorphisms of CYP3A4, GSTT1, GSTM1, GSTP1 and NQO1 were associated with the risk of developing aplastic anemia and with the response to immunosuppressive therapy.
We analyzed the impact of the polymorphisms in CYP4501A1 and GSTM1 and GSTT1 genes on the susceptibility and disease severity in 200 patients with AA and compared the frequency with the normal population.
