Neurodevelopmental disorder with microcephaly, impaired language, epilepsy, and gait abnormalities (NEDMILEG) is characterized by global developmental delay apparent in infancy. Affected individuals have delayed walking with variable gait abnormalities, including ataxia and spasticity, impaired intellectual development with poor or absent speech and language, and progressive microcephaly. Dysmorphic facial features may also be observed. Most patients have early-onset seizures; some may develop a demyelinating peripheral neuropathy. The clinical features suggest involvement of both the central and peripheral nervous systems (Manole et al., 2020). [from OMIM]

Neurodevelopmental disorder with microcephaly, language delay, and gait abnormalities (NEDMILG) is an autosomal recessive disorder characterized by global developmental delay apparent in infancy. Affected individuals have delayed walking with variable gait abnormalities, impaired intellectual development with poor or absent speech and language, and progressive microcephaly. More variable features include hypotonia, early-onset seizures, and a peripheral demyelinating or axonal peripheral sensorimotor neuropathy. The disease follows a neurodegenerative course in many patients; clinical features suggest involvement of both the central and peripheral nervous systems (Manole et al., 2020). [from OMIM]
