FMR1 and Intellectual disability: In a complementary approach, we analyzed the overlap between the 227 orthologs of DEX genes and ASD-associated genes [32] from SFARI database (859 genes), FMRP-associated genes from Darnell and colleagues [33] (842 genes), intellectual disability-associated genes from multiple sources [34], schizophrenia-associated genes ([35] and OMIM, 196 genes) and synaptome-associated genes [36] (SynaptomeDB, 1876 genes).
