ABSTRACT
Abstract A single nucleotide polymorphism of rs1360780 in the FKBP5 gene is associated with a predisposition to developing major depressive disorder (MDD). We investigated interactive effects allelic variants, DNA methylation, and diagnosis MDD on structural changes entire brain. One hundred fourteen patients eighty-eight healthy controls underwent T1-weighted magnetic resonance imaging genotyping, including methylation intron 7. analyzed volume cortical subcortical regions thickness using FreeSurfer. Significant genotype-by-diagnosis interactions were observed for volumes left pars triangularis, supramarginal gyrus, superior parietal lobule, right frontomarginal, posterior midcingulate gyrus. The T allele was significant reductions these brain only group except showed positive correlation transverse frontopolar gyrus C homozygote group. Our findings suggest that its epigenetic could have influence morphologic several involved emotion regulation, this process may be development MDD.
