Abstract

We investigated the presence of mutations in the pantothenate kinase (PANK2) gene in a 27-year-old male Chinese patient with atypical pantothenate kinase-associated neurodegeneration (PKAN), formerly Hallervorden-Spatz syndrome. Automated DNA sequence analyses revealed compound heterozygous mutations in the exon 3 and 5. This patient had a 10-year history of PKAN characterized by a slight tremor of the right hand when writing at onset and a slow progressive rigidity of the neck and the right arm and resting tremor in upper extremities. Dysarthria, dysphagia, and dystonic-athetoid movements of the face and right fingers were marked. Magnetic resonance showed the typical "eye-of-the-tiger" sign.

摘要

我们对一名27岁的中国男性非典型泛酸激酶相关神经变性(PKAN,既往称为Hallervorden-Spatz综合征)患者的泛酸激酶(PANK2)基因进行了突变检测。自动DNA序列分析显示第3外显子和第5外显子存在复合杂合突变。该患者有10年PKAN病史,起病时表现为书写时右手轻微震颤,颈部和右臂缓慢进行性僵硬以及上肢静止性震颤。明显存在构音障碍、吞咽困难以及面部和右手手指的张力障碍性手足徐动症。磁共振成像显示典型的“虎眼征”。
