Summaries for Pontocerebellar Hypoplasia, Type 5

NIH Rare Diseases : 54 The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.Orpha Number: 166068Disease definitionPontocerebellar hypoplasia type 5 (PCH5) is a very rare severe form of PCH (see this terme) with prenatal onset and characterized by fetal onset of clonus or seizures-like activity persisting in infancy and microencephaly leading to early postnatal death. There is significant overlap both in phenotype and in genotype between pontocerebellar hypoplasia types 4 and 5.EpidemiologyPCH5 is reported in 3 siblings to date.Clinical descriptionPCH5, clinically resembling PCH4 (see this term), is characterized by fetal onset of clonus or seizure-like episodes, microcephaly, cerebellar hypoplasia persisting in infancy and microencephaly leading to early postnatal death.EtiologyPCH5 is caused by a compound heterozygosity for p.A307S plus splice site mutation in the gene. PCH5 transmission is autosomal recessive.Diagnostic methodsClinically similar to PCH4, PCH5 is demonstrated on autopsy. MRI demonstrates inferior olivary dysplasia, and pontocerebellar hypoplasia with the vermis much more degenerated than cerebellar hemispheres. Pathological findings show and increased degeneration with Purkinje and granule cells in the vermis.Antenatal diagnosisAntenatal diagnosis is possible by ultrasonic assessment of cerebellar width at 16-18 weeks gestation.Visit the Orphanet disease page for more resources.

MalaCards based summary : Pontocerebellar Hypoplasia, Type 5, also known as pontocerebellar hypoplasia type 5, is related to pontocerebellar hypoplasia and pontocerebellar hypoplasia type 1. An important gene associated with Pontocerebellar Hypoplasia, Type 5 is TSEN54 (TRNA Splicing Endonuclease Subunit 54). Affiliated tissues include cerebellum, brain and pons, and related phenotypes are seizures and microcephaly

Disease Ontology : 12 A pontocerebellar hypoplasia that is characterized by severe olivopontocerebellar hypoplasia and degeneration leading to early lethality, has material basis in autosomal recessive inheritance of mutation in the TSEN54 gene.

OMIM : 58 Pontocerebellar hypoplasia (PCH) refers to a heterogeneous group of disorders characterized by an abnormally small cerebellum and brainstem (summary by Patel et al., 2006). For a phenotypic description and a discussion of genetic heterogeneity of pontocerebellar hypoplasia, see PCH1 (607596). (610204)

UniProtKB/Swiss-Prot : 76 Pontocerebellar hypoplasia 5: A form of pontocerebellar hypoplasia, a disorder characterized by structural defects of the pons and cerebellum. Brain MRI shows an abnormally small cerebellum and brainstem, decreased cerebral white matter, and a thin corpus callosum.
