  • Mental retardation, X-linked 72 (MRX72) [MIM:300271]: A disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period. Intellectual deficiency is the only primary symptom of non-syndromic X-linked mental retardation, while syndromic mental retardation presents with associated physical, neurological and/or psychiatric manifestations. MRX72 patients can manifest autism spectrum disorder, seizures and macrocephaly as additional features. {ECO:0000269 PubMed:20159109}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Waisman syndrome (WSMN) [MIM:311510]: A neurologic disorder characterized by delayed psychomotor development, intellectual disability, and early-onset Parkinson disease. {ECO:0000269 PubMed:25434005}. Note=The disease is caused by mutations affecting the gene represented in this entry.
