Pathogenic variants in the SACS gene (OMIM #604490) cause autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS). ARSACS is a neurodegenerative early-onset progressive disorder, originally described in French Canadians, but later observed elsewhere.(1) Whole-exome sequencing of a large group of patients with unclassified progressive myoclonus epilepsies (PMEs) identified 2 patients bearing SACS gene mutations.(2) We detail the PME clinical features associated with SACS mutations and suggest the inclusion of the SACS gene in diagnostic screening of PMEs.
SACS 基因(OMIM #604490)中的致病性变异导致常染色体隐性痉挛性共济失调-沙格奈(ARSACS)。ARSACS 是一种神经退行性疾病,为早发性进行性疾病,最初在法裔加拿大人中描述,但后来在其他地方也有观察到。(1)对一大群未分类的进行性肌阵挛性癫痫(PME)患者进行全外显子组测序,发现 2 名患者携带 SACS 基因突变。(2)我们详细描述了与 SACS 突变相关的 PME 临床特征,并建议将 SACS 基因纳入 PME 的诊断筛查。
