Summaries for Cerebellar Atrophy with Seizures and Variable Developmental...

OMIM : 57 Cerebellar atrophy with seizures and variable developmental delay (CASVDD) is an autosomal recessive neurologic disorder characterized by cerebellar ataxia associated with atrophy of the cerebellar vermis on brain imaging. Most patients also have onset of severe refractory seizures in the first year of life and show global developmental delay, compatible with epileptic encephalopathy (summary by Edvardson et al., 2013). However, at least 1 patient with normal cognitive development and only 1 febrile seizure has been reported (Valence et al., 2019), suggesting significant clinical variability of this disorder. (618501)

MalaCards based summary : Cerebellar Atrophy with Seizures and Variable Developmental Delay, is also known as casvdd. An important gene associated with Cerebellar Atrophy with Seizures and Variable Developmental Delay is CACNA2D2 (Calcium Voltage-Gated Channel Auxiliary Subunit Alpha2delta 2). Affiliated tissues include brain and eye.
