Abstract
Paroxysmal dyskinesia (PD) is a clinically and genetically heterogeneous group of diseases characterized by episodically recurrent involuntary movements and classified into three groups: paroxysmal kinesigenic dyskinesia (PKD), paroxysmal non-kinesigenic dyskinesia (PNKD) and paroxysmal exercise-induced dyskinesia (PED). The breakthrough of genetics of PD was the identification of PRRT2 mutations in 2011. Following this, it has been well recognized that there is increasing genetic and clinical overlaps between PD and other paroxysmal neurologic disorders, including epilepsy, hemiplegic migraine, episodic ataxia and migraine. Advancement in genetics of PD has contributed to well-addressed genotypic-phenotypic correlations of the above diseases, which help greatly in improving the efficiency of genetic diagnosis and thus benefit more treatable patients. The rapidly-accumulated genetic knowledge has also shed light on understandings of the normal functions of the related genes and the underlying pathogenesis how these mutated genes to cause diseases. Furthermore, the reversibility of PD may be the key to unravel the mechanisms of other irreversible neurodegenerative diseases and inspire potential targets of treatment in the future.
