Marinesco-Sjögren syndrome (MSS) is an autosomal recessive multiorgan disorder with clinical and genetic heterogeneity. The key features of MSS include cerebellar ataxia, early bilateral cataracts, delayed motor development, and to a varying degree mental retardation. ⋯ In addition, both patients presented with external ophthalmoplegia and paralytic dysphagia. Sequencing of all 10 exons of the SIL1 gene did not detect any SIL1 mutation in our patients.
