A new case of concurrent existence of PRRT2-associated paroxysmal movement disorders with c.649dup variant and 16p11.2 microdeletion syndrome
The PRRT2 gene located at 16p11.2 encodes proline-rich transmembrane protein 2. In recent reviews, clinical spectrum caused by pathogenic PRRT2 variants is designated as PRRT2-associated paroxysmal movement disorders, which include paroxysmal kinesigenic dyskinesia, benign familial infantile epilepsy, and infantile convulsions with choreoathetosis, and hemiplegic migraine. The recurrent 16p11.2 microdeletion encompassing PRRT2 has also been reported to cause neurodevelopmental syndrome, associated with autism spectrum disorder.
