Summaries for Mental Retardation, X-Linked, Syndromic 13

Genetics Home Reference : 25 PPM-X syndrome is a condition characterized by psychotic disorders (most commonly bipolar disorder), a pattern of movement abnormalities known as parkinsonism, and mild to severe intellectual disability. Other symptoms include increased muscle tone and exaggerated reflexes. Affected males may have enlarged testes (macro-orchidism). Not all affected individuals have all these symptoms, but most have intellectual disability. Males with this condition are typically more severely affected than females, who usually have only mild intellectual disability.

MalaCards based summary : Mental Retardation, X-Linked, Syndromic 13, also known as ppm-x syndrome, is related to renpenning syndrome and mental retardation-hypotonic facies syndrome, x-linked, and has symptoms including ataxia, seizures and tremor. An important gene associated with Mental Retardation, X-Linked, Syndromic 13 is MECP2 (Methyl-CpG Binding Protein 2). Affiliated tissues include testes.

Disease Ontology : 12 A syndromic X-linked intellectual disability characterized by moderate intellectual deficit, manic-depressive psychosis, pyramidal signs and macroorchidism that has material basis in mutation in the MECP2 gene on chromosome Xq28.

OMIM : 54 The MECP2 gene is mutated in Rett syndrome (RTT; 312750), a severe neurodevelopmental disorder that almost always... (300055) more...

UniProtKB/Swiss-Prot : 66 Mental retardation, X-linked, syndromic, 13: A disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period. MRXS13 patients manifest mental retardation associated with other variable features such as spasticity, episodes of manic depressive psychosis, increased tone and macroorchidism.
