Summaries for Cortical Dysplasia, Complex, with Other Brain Malformations 6

UniProtKB/Swiss-Prot : 76 Cortical dysplasia, complex, with other brain malformations 6: A disorder of aberrant neuronal migration and disturbed axonal guidance. Affected individuals have microcephaly, ataxia, and severe delayed psychomotor development. Brain imaging shows variable malformations of cortical development, including white matter streaks, dysmorphic basal ganglia, corpus callosum abnormalities, brainstem and cerebellar hypoplasia, cortical dysplasia, polymicrogyria.

MalaCards based summary : Cortical Dysplasia, Complex, with Other Brain Malformations 6, is also known as cdcbm6, and has symptoms including ataxia An important gene associated with Cortical Dysplasia, Complex, with Other Brain Malformations 6 is TUBB (Tubulin Beta Class I). Affiliated tissues include brain, and related phenotypes are microphthalmia and retinal dysplasia

Disease Ontology : 12 A complex cortical dysplasia with other brain malformations that has material basis in heterozygous mutation in the TUBB gene on chromosome 6p21.
