Here, we discuss recent updates on WIPI4's mechanistic role in autophagy and link the neuropathological manifestations of BPAN's biphasic infantile onset (epilepsy, autism) and adolescent onset (dystonic, Parkinsonism, dementia) phenotypes to neurological consequences of autophagy impairment that are now known or emerging in many other neurodevelopmental and neurodegenerative disorders.
The identification of WDR45 mutations provides further evidence that WES plays an important role in the diagnosis of neurological disorders with common phenotypes and that WDR45 mutations are associated with neurological disorders and are not very rare in Chinese female pediatric patients with DD and/or epilepsy.
