Summary

Neurodevelopmental disorder with epilepsy, spasticity, and brain atrophy (NEDESBA) is an autosomal recessive disorder characterized by severely impaired global development apparent soon after birth. Affected individuals develop seizures in the first year of life and achieve almost no psychomotor progress, resulting in feeding difficulties and an inability to walk or speak. Other features include hypotonia, peripheral spasticity with contractures, cortical visual impairment, and dysmorphic features, including microcephaly. Death in childhood may occur (summary by Van Bergen et al., 2020). Van Bergen et al. (2020) noted that the molecular mechanism of this disorder can be classified into a group of similar phenotypes resulting from mutations in genes associated with transport protein particles, sometimes referred to as 'TRAPPopathies' (review by Sacher et al., 2019).
