Pontocerebellar Hypoplasia, Type 2b; Pch2b

Description

Pontocerebellar hypoplasia (PCH) represents a heterogeneous group of disorders characterized by an abnormally small cerebellum and brainstem. PCH type 2 is characterized by progressive microcephaly from birth combined with extrapyramidal dyskinesia and chorea, epilepsy, and normal spinal cord findings (Barth, 1993).For a phenotypic description and a discussion of genetic heterogeneity of PCH, see PCH1 (OMIM ).
