Summaries for Pontocerebellar Hypoplasia

NIH Rare Diseases : 50 pontocerebellar hypoplasia (pch) is a group of conditions affecting the brain characterized by underdevelopment of the cerebellum and pons. the cerebellum normally coordinates movement and the pons (located in the brainstem) transmits signals from the cerebellum to the rest of the brain. several forms of pch have been described, each having some different signs and symptoms but all characterized by problems with movement, delayed psychomotor development, and intellectual disability. although each form has a different genetic cause, they are all inherited in an autosomal recessive manner. many children with pch live only into infancy or childhood, although some individuals have lived into adulthood. treatment is symptomatic and supportive. last updated: 12/18/2012

MalaCards based summary : Pontocerebellar Hypoplasia, also known as pch, is related to pontocerebellar hypoplasia type 4 and pontocerebellar hypoplasia type 5. An important gene associated with Pontocerebellar Hypoplasia is TSEN54 (TRNA Splicing Endonuclease Subunit 54), and among its related pathways/superpathways are Gene Expression and tRNA processing. Affiliated tissues include brain, cerebellum and pons.

Genetics Home Reference : 25 Pontocerebellar hypoplasia is a group of related conditions that affect the development of the brain. The term "pontocerebellar" refers to the pons and the cerebellum, which are the brain structures that are most severely affected in many forms of this disorder. The pons is located at the base of the brain in an area called the brainstem, where it transmits signals between the cerebellum and the rest of the brain. The cerebellum, which is located at the back of the brain, normally coordinates movement. The term "hypoplasia" refers to the underdevelopment of these brain regions.
