Paroxysmal dyskinesias are a group of hyperkinetic movement disorders characterized by episodes of dystonia, chorea, athetosis, and ballism that appear isolated or in combination without loss of consciousness. We can differentiate various forms of paroxysmal dyskinesia based on genotypic and phenotypic features: Paroxysmal kinesigenic...

Proline-rich transmembrane protein 2 (PRRT2) is a neuron-specific protein implicated in the control of neurotransmitter release and neural network stability. Accordingly, PRRT2 loss-of-function mutations associate with pleiotropic paroxysmal neurological disorders, including paroxysmal kinesigenic dyskinesia, episodic ataxia, benign familial...

The striatal-enriched protein tyrosine phosphatase (STEP) is a brain-specific phosphatase involved in synaptic transmission. The current hypothesis on STEP function holds that it opposes synaptic strengthening by dephosphorylating and inactivating key neuronal proteins involved in synaptic plasticity and intracellular signaling, such as the MAP...
