Single nucleotide polymorphisms UGT1A4 142T > G, L48V (*3), UGT1A4 70C > A, P24T (*2) and UGT2B7 802C > T, H268Y (*2) were determined in 40 women (47 pregnancies) with epilepsy treated with LTG.
The aim of this study was to investigate the effect of two UGT1A4 gene polymorphisms, UGT1A4 (70C > A) and UGT1A4 (142 T > G), on the levels and efficacy of LTG in Han Chinese patients with epilepsy.
In this study, single nucleotide polymorphisms, P24T and L48V, of the UGT1A4 enzyme have been investigated in a Turkish population of patients with epilepsy (n=131) by comparing serum levels of LTG of wild type and polymorphic subjects.
