We compared ourDEG analysis results with the genes related to RTT and RTT-like syndromesreported in the literature and observed that several previously reportedgenes such as MECP2, FOXG1, CACNA1G, SATB2, GABBR2, MEF2C, KCNJ10, and CUX2(39) were also identified in our analysis. The gene discussed is FOXG1; the disease is Rett syndrome.
