Summaries for Galactosialidosis

OMIM : 54 Galactosialidosis is a lysosomal storage disease associated with a combined deficiency of beta-galactosidase (611458)... (256540) more...

MalaCards based summary : Galactosialidosis, also known as neuraminidase deficiency with beta-galactosidase deficiency, is related to mannosidosis and shprintzen-goldberg syndrome, and has symptoms including seizures, intellectual disability and coarse facial features. An important gene associated with Galactosialidosis is CTSA (Cathepsin A), and among its related pathways/superpathways are Metabolism and Metabolism of proteins. The drug Krestin has been mentioned in the context of this disorder. Affiliated tissues include bone, bone marrow and skin.

Genetics Home Reference : 25 Galactosialidosis is a condition that affects many areas of the body. The three forms of galactosialidosis are distinguished by the age at which symptoms develop and the pattern of features.

NIH Rare Diseases : 50 galactosialidosis is an autosomal recessive lysosomal storage disorder caused by mutations in the ctsa gene. it is characterized by coarse facial features, macular cherry-red spots, angiokeratoma (dark red spots on the skin), vertebral deformities, epilepsy, action myoclonus, and ataxia. there are three different types of galactosialidosis: early infantile, late infantile and juvenile/adult. the three forms of galactosialidosis are distinguished by the age at which symptoms develop and the pattern of features. last updated: 5/16/2011

UniProtKB/Swiss-Prot : 66 Galactosialidosis: A lysosomal storage disease associated with a combined deficiency of beta-galactosidase and neuraminidase, secondary to a defect in cathepsin A. All patients have clinical manifestations typical of a lysosomal disorder, such as coarse facies, cherry red spots, vertebral changes, foam cells in the bone marrow, and vacuolated lymphocytes. Three phenotypic subtypes are recognized. The early infantile form is associated with fetal hydrops, edema, ascites, visceromegaly, skeletal dysplasia, and early death. The late infantile type is characterized by hepatosplenomegaly, growth retardation, cardiac involvement, and a normal or mildly affected mental state. The juvenile/adult form is characterized by myoclonus, ataxia, angiokeratoma, mental retardation, neurologic deterioration, absence of visceromegaly, and long survival.
