Summary

Developmental and epileptic encephalopathy-78 (DEE78) is a severe neurologic disorder characterized by onset of refractory seizures in the first days or months of life followed by severely impaired intellectual development. Additional features may include cortical visual impairment, hypotonia, and abnormal movements, such as spasticity (summary by Butler et al., 2018). One family with an attenuated disease course has been reported (Maljevic et al., 2019). For a general phenotypic description and a discussion of genetic heterogeneity of DEE, see 308350. [from OMIM]
