No significant interaction of diagnosis (MDD patients, HCs) and MAOA-uVNTR genotype (MAOA-H, MAOA-L) on OFC cortical thickness was revealed for any of the regions (left OFC (F(1,69) = 0.345, p = 0.559), right OFC (F(1,69) = 0.010, p = 0.920), left medial OFC (F(1,69) = 1.544, p = 0.218), right medial OFC (F(1,69) = 0.509, p = 0.478), left lateral OFC (F(1,69) = 0.020, p = 0.889), right lateral OFC (F(1,69) = 0.063, p = 0.802); Table 4). Here, MAOA is linked to major depressive disorder.
