Some authors found that ABCC2 −24C>T, 3972C>T polymorphisms, and one ABCC2 haplotype was associated with ASMs resistance, whereas ABCC2 1249G>A and ABCB1 3435C>T polymorphisms were not associated with ASMs resistance in Chinese patients with epilepsy.51 The gene discussed is ABCC2; the disease is epilepsy.
