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 ). Genetic Heterogeneity of Pontocerebellar Hypoplasia Type 2PCH2B (OMIM ) is caused by mutation in the TSEN2 gene (OMIM ) on chromosome 3p25, and PCH2C (OMIM ) is caused by mutation in the TSEN34 gene (OMIM ) on chromosome 19q13. PCH2D (OMIM ) is caused by mutation in the SEPSECS gene (OMIM ) on chromosome 4p15. PCH2E (OMIM ) is caused by mutation in the VPS53 gene (OMIM ) on chromosome 17p13. PCH2F (OMIM ) is caused by mutation in the TSEN15 gene (OMIM ) on chromosome 1q25. The TSEN2 and TSEN34 genes encode catalytic subunits of the tRNA splicing endonuclease, whereas the TSEN54 gene encodes a noncatalytic subunit. The SEPSECS gene is also involved in tRNA processing.
