" /> Marinesco-sjogren syndrome - CISMeF





Preferred Label : Marinesco-sjogren syndrome;

Symbol : MSS;

CISMeF acronym : MSS;

Type : Phenotype, molecular basis known;

Description : Marinesco-Sjogren syndrome is an autosomal recessive disorder characterized primarily by congenital cataracts, cerebellar ataxia, progressive muscle weakness due to myopathy, and delayed psychomotor development. Other features include short stature, hypergonadotrophic hypogonadism, and skeletal deformities due to muscle weakness. MSS is genetically distinct from congenital cataracts, facial dysmorphism, and neuropathy (CCFDN; 604168), which is caused by mutation in the CTDP1 gene (604927) on chromosome 18q23, although the 2 disorders share some overlapping features, including congenital cataracts, delayed psychomotor development, and ataxia. The major distinguishing features are the presence of peripheral neuropathy, facial dysmorphism, and microcornea in CCFDN (Lagier-Tourenne et al., 2003).;

Inheritance : Autosomal recessive;

Molecular basis : Caused by mutation in the SIL1 nucleotide exchange factor gene (SIL1, 608005.0001);

Laboratory abnormalities : Increased serum creatine kinase;

Prefixed ID : #248800;
