Poirier-Bienvenu neurodevelopmental syndrome (POBINDS) is a neurologic disorder characterized in most cases by early-onset seizures and variably impaired intellectual development (ID). The severity of neurologic impairment is highly variable: some patients may have refractory seizures and be bedridden with no meaningful speech, whereas others may have treatment-responsive seizures and achieve normal psychomotor development (summary by Li et al., 2019).
