PRRT2-Related Conditions (Episodic Kinesigenic Dyskinesia, Benign Familial Infantile Seizures, Familial Infantile Convulsions with Paroxysmal Choreoathetosis)

PRRT2-related conditions encompass paroxysmal kinesigenic dyskinesia and benign familial infantile seizures, with some individuals experiencing both episodic movement disorders and seizures. Attacks are brief, often triggered by movement or startle, and neurologic examination between episodes is typically normal. Genetic testing confirms the diagnosis and supports counseling and treatment planning.
