Autosomal recessive spinocerebellar ataxia type 4 (SCAR4) is a type of SCA that is a group of hereditary diseases characterized by gait ataxia. The main clinical features of SCAR4 are progressive cerebellar ataxia, pyramidal signs, neuropathy, and macrosaccadic intrusions. To date, many gene dysfunctions have been reported to be associated with SCAR4.
Here, we report a novel compound heterozygous mutation, c.3288delA (p.Asp1097ThrfsTer6), in the gene in a young female Chinese patient. The patient found something wrong with her legs about 10 years ago and presented with the typical characteristics of SCAR4 when she came to the hospital, including ataxia, neuropathy, and positive pyramidal signs. She was then diagnosed with SCAR4 and went home with symptomatic schemes.
SCAR4 is a hereditary disease characterized by ataxia, pyramidal signs, neuropathy, and macrosaccadic intrusions. We report a novel compound heterozygous mutation, c.3288delA (p.Asp1097ThrfsTer6), in the gene, which enriches the gene mutation spectrum and provides additional information about SCAR4.
常染色体隐性遗传性脊髓小脑共济失调4型(SCAR4)是脊髓小脑共济失调(SCA)的一种类型,SCA是一组以步态共济失调为特征的遗传性疾病。SCAR4的主要临床特征为进行性小脑共济失调、锥体束征、神经病变和巨扫视侵入。迄今为止,已有许多基因功能障碍被报道与SCAR4相关。
在此,我们报告一名年轻中国女性患者的该基因存在一种新的复合杂合突变,即c.3288delA(p.Asp1097ThrfsTer6)。该患者约10年前发现腿部有异常,来院时表现出SCAR4的典型特征,包括共济失调、神经病变和锥体束征阳性。随后她被诊断为SCAR4,并带着对症方案回家。
