MDD is associated with the rs2032582 (<i>G2677T</i>) and rs1128503 (<i>C1236T</i>) single-nucleotide polymorphisms (SNPs) of <i>ABCB1</i> but not with rs1045642, rs2032583, rs2235040, and rs2235015.
Our results indicated that MDR1 variants G2677T and C3435T are not associated with therapeutic response to paroxetine in patients with major depressive disorder.
Our results show that SERTPR-LL genotype might predispose significantly better paroxetine treatment response compared to SS genotype in MDD patients and that variants G2677T and C3435T are not associated with therapeutic response to paroxetine in patients with major depressive disorder.
