A 38-year-old woman was diagnosed autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) with a novel pathogenic variant in the gene presented with gradually progressive spastic ataxia since the age of 2 years; then, she became wheelchair-bound at the age of 28 years.
The patient presented a combination of cerebellar dysfunctions e.g., gaze-evoked nystagmus, scanning speech, finger dysmetria, and wide-based gait, lower limb spasticity, and typical funduscopic examination which was a hypermyelinated nerve fibers radiating from the optic disc.
At present, ARSACS is recognized as a rare, worldwide, inherited movement disorder in which we should to aware of a diagnosis of this disorder in the patient who is presented with gene negative early-onset spastic ataxia.
一名 38 岁女性被诊断为常染色体隐性痉挛性共济失调查尔洛夫-萨格奈(ARCSACS),携带基因中的新致病性变异,自 2 岁起逐渐出现痉挛性共济失调;随后,她在 28 岁时坐上了轮椅。
患者表现出小脑功能障碍的组合,如眼球震颤、扫视言语、手指运动障碍和宽基底步态、下肢痉挛以及典型的眼底检查,即从视盘放射出的高髓鞘化神经纤维。
目前,ARCSACS 被认为是一种罕见的、全球性的遗传性运动障碍,对于具有基因阴性的早发性痉挛性共济失调的患者,我们应该认识到这种疾病的诊断。
