SEPTIN3 and mental disorder: In addition, an associationof the genes, previously demonstrated to be involved in thedevelopment of mental disorders (MEF2C, EXOC4, CYP2D6,FAM109B, SEPT3, NAGA, TCF20, NDUFA6), was determinedwith cognitive functioning in mentally healthy individuals.In the study of genes associated with cognitive impairment,the role of genes involved in epigenetic regulation (includingDNA methylation, histone modification, and chromatinremodeling) was established.
