The Kearns-Sayre syndrome (KSS) is a distinctive type of progressive external ophthalmoplegia, characterized by pigmentary degeneration of the retina, heart block, elevated concentration of cerebrospinal fluid protein, and abnormal muscle mitochondria. Previously described cases have all been sporadic. Consequently, viral infections and autoimmune disorders have been proposed as etiologies. The occurrence of KSS in two brothers suggests that genetic factors may play a role in the pathogenesis of some cases.
卡恩斯-塞尔综合征(KSS)是一种独特类型的进行性眼外肌麻痹,其特征为视网膜色素变性、心脏传导阻滞、脑脊液蛋白浓度升高以及肌肉线粒体异常。先前报道的病例均为散发性。因此,有人提出病毒感染和自身免疫性疾病可能是其病因。两兄弟均患KSS这一情况表明,遗传因素可能在某些病例的发病机制中起作用。
