Early-onset bradykinetic rigid syndrome and reflex seizures in a child with PURA syndrome

PURA syndrome is a distinct form of developmental encephalopathy, characterized by early-onset hypotonia, severe developmental delay, intellectual disability, epilepsy and respiratory and gastrointestinal disorders. We report a child with PURA syndrome, harbouring a previously described mutation, whose phenotype included two peculiar aspects: (1) hypokinetic-rigid syndrome, which was part of the clinical presentation from an early stage of the disease, and (2) reflex seizures, consisting of a series of spasms. We provide detailed clinical description and video recordings demonstrating both these aspects that are newly described in PURA syndrome.
