Summaries for Pontocerebellar Hypoplasia, Type 10

OMIM : 56 Pontocerebellar hypoplasia type 10 is an autosomal recessive neurodevelopmental and neurodegenerative disorder characterized by severely delayed psychomotor development, progressive microcephaly, spasticity, seizures, and brain abnormalities, including brain atrophy and delayed myelination. Some patients have dysmorphic features and an axonal sensorimotor neuropathy (summary by Karaca et al., 2014 and Schaffer et al., 2014). For a general phenotypic description and a discussion of genetic heterogeneity of PCH, see PCH1 (607596). (615803)

MalaCards based summary : Pontocerebellar Hypoplasia, Type 10, also known as pontocerebellar hypoplasia type 10, is related to pontocerebellar hypoplasia and constipation, and has symptoms including muscle spasticity An important gene associated with Pontocerebellar Hypoplasia, Type 10 is CLP1 (Cleavage Factor Polyribonucleotide Kinase Subunit 1). Affiliated tissues include brain, cerebellum and pons, and related phenotypes are hyperreflexia and delayed speech and language development

Disease Ontology : 12 A pontocerebellar hypoplasia that is characterized by severe developmental delays, progressive microcephaly, spasticity and seizure, has material basis in autosomal recessive inheritance of mutation in the CLP1 gene.

UniProtKB/Swiss-Prot : 73 Pontocerebellar hypoplasia 10: A form of pontocerebellar hypoplasia, a disorder characterized by structural defects of the pons and cerebellum, evident upon brain imaging. PCH10 features include cortical dysgenesis marked by a simplified gyral pattern, cortical atrophy, mild or focal cerebellar vermian volume loss, delayed myelination, progressive microcephaly, global growth and developmental delays, severe intellectual disabilities, and seizures refractory to treatment.
