Hereditary chin tremor (HCT) is characterized by rhythmical, involuntary movements of the chin muscles usually inherited in an autosomal dominant pattern. We describe a 74-year old man with familial, childhood-onset chin tremor, and a 3-year history of progressive hand tremor, gait difficulty, and other parkinsonian features. Since chin tremor often occurs in Parkinson's disease (PD), a coexistent HCT may not be recognized unless past and family history of tremor is carefully explored.
遗传性颏部震颤（HCT）的特征是颏部肌肉有节奏的、不自主运动，通常呈常染色体显性模式遗传。我们描述了一名74岁男性，有家族性儿童期起病的颏部震颤，并有3年进行性手部震颤、步态障碍及其他帕金森病特征的病史。由于颏部震颤常发生于帕金森病（PD），除非仔细探究震颤的既往史和家族史，否则可能无法识别并存的HCT。
