More generally, genetic aberrations of many of the differentially methylated genes in our study, i.e., TRIO, NRXN2, SYN2, CACNA1E, DNM1 and RAB11B, have been associated with movement disorders, cognitive and visual impairments and brain abnormalities (e.g., atrophy, white matter apoplasia) [69]. This evidence concerns the gene SYN2 and movement disorder.
