Summary Genetic‐neuroimaging studies could identify new potential endophenotypes of major depressive disorder ( MDD ). Morphological and functional alterations may be attributable to genetic factors that regulate neurogenesis and neurodegeneration. Given that the association between gene polymorphisms and brain morphology or function has varied across studies, this systematic review aims at evaluating and summarizing all available genetic‐neuroimaging studies. Twenty‐eight gene variants were evaluated in 64 studies by structural or functional magnetic resonance imaging. Significant genetic‐neuroimaging associations were found in monoaminergic genes, BDNF genes, glutamatergic genes, HPA axis genes, and the other common genes, which were consistent with common hypotheses of the pathogenesis of MDD .
