Association of gene polymorphisms with age of onset and HDRS scores in MDD patients. (A) Age of onset (years) of common GG homozygotes and A allele carriers (AA/AG genotype) of SLC1A2 rs1885343 and (B) HDRS scores of common CC homozygotes and G allele carriers (GG/CG genotype) of SLC1A2 rs4755404 in MDD patients (n = 100). Bars with black or white fill represent mean data, error bars SEM. *P < 0.05; independent samples t test. HDRS, Hamilton Depression Rating Scale; MDD, major depressive disorder; SEM, standard error of the mean
