摘要: Two French-Canadian sibs with cerebellar ataxia and dysarthria were seen in our neurogenetics clinic. The older brother had global developmental delay spastic paraplegia. Brain MRIs from these two affected individuals showed moderate to severe atrophy. To identify the genetic basis for their disease, we conducted a whole exome sequencing (WES) investigation using genomic DNA prepared healthy father. We identified mutations SIL1 gene, which is reported cause Marinesco-Sjogren syndrome. This study emphasizes how diagnosis of patients ataxic gait atrophy may benefit WES condition.
