Summaries for Encephalopathy, Progressive, Early-Onset, with Brain Atrophy and...

OMIM : 58 PEBAT is an autosomal recessive neurodevelopmental disorder characterized by severely delayed psychomotor development apparent soon after birth or in infancy, profound intellectual disability, poor or absent speech, and seizures. Most patients are never able to walk due to hypotonia or spasticity. Brain imaging shows cerebral and cerebellar atrophy, thin corpus callosum, and secondary hypomyelination. The disorder shows progressive features, including microcephaly, consistent with a neurodegenerative process (summary by Miyake et al., 2016; Flex et al., 2016). (617193)

MalaCards based summary : Encephalopathy, Progressive, Early-Onset, with Brain Atrophy and Thin Corpus Callosum, is also known as pebat. An important gene associated with Encephalopathy, Progressive, Early-Onset, with Brain Atrophy and Thin Corpus Callosum is TBCD (Tubulin Folding Cofactor D). Affiliated tissues include brain, tongue and eye, and related phenotypes are hypertelorism and intellectual disability

UniProtKB/Swiss-Prot : 76 Encephalopathy, progressive, early-onset, with brain atrophy and thin corpus callosum: An autosomal recessive disease with neurodevelopmental and neurodegenerative features. PEBAT is characterized by early-onset cortical atrophy, hypomyelination, microcephaly, thin corpus callosum, delayed psychomotor development, developmental regression, intellectual disability, seizures, optic atrophy, muscle weakness and atrophy, spastic quadriplegia, and respiratory insufficiency due to hypotonia.
