Two susceptibility loci have been identified in which no specific gene of interest has been definitively identified. The MDD1 locus is located at 12q22-q23.2 and is most strongly linked to major depression in males. [16] The MDD2 locus is located at 15q25.2-q26.2 and has been associated with early onset or recurrent episodes of depression. [17]
