RHOBTB2 and Dyskinesia: Table 1 provides a list of predominant dyskinesia genes organized according to function detailing inheritance, phenotypes and potential treatments. We have chosen to discuss eight dyskinesia genes in detail on the basis of high prevalence in clinical practice in the case of five genes (PRRT2, PNKD, SLC2A1, KCNMA1, ADCY5) and the recent discovery and newly described phenotypes (RHOBTB2, TBC1D24, PDE2A).
