Moreover, YY1 interacts with the methyl-CpG binding protein 2 (MECP2) protein and regulates the expression of ANT1 encoding a mitochondrial adenine nucleotide translocase enzyme associated with Rett syndrome which is an ASD-related neurodevelopmental disorder with loss of motor skills and speech [108]. This evidence concerns the gene MECP2 and atypical Rett syndrome.
