Since the original report in 2001 [2], in which the authors described the movement disorder in the affected family members as “Familial Dyskinesia with Facial Myokymia”, the phenotypic spectrum associated with ADCY5 mutations has expanded and a more detailed delineation of movement disorders has been provided in subsequent reports [3], [4], [5], [7]. The gene discussed is ADCY5; the disease is movement disorder.
