Summaries for Mannosidosis, Beta

About this section
UniProtKB/Swiss-Prot:68 Mannosidosis, beta A, lysosomal: An autosomal recessive lysosomal storage disease of glycoprotein catabolism. Clinical features are heterogeneous with a wide range of symptoms and age of onset. The disease is associated with a range of neurological involvement, including various degrees of mental retardation in most of the cases, hearing loss and speech impairment, hypotonia, epilepsy and peripheral neuropathy. Affected individuals have a profound reduction in beta A mannosidase activity in plasma, fibroblasts and leukocytes.

MalaCards based summary: Mannosidosis, Beta, also known as beta-mannosidosis, is related to malignant gastric germ cell tumor and marginal zone b-cell lymphoma, and has symptoms including hearing impairment, seizures and abnormal facial shape. An important gene associated with Mannosidosis, Beta is MANBA (Mannosidase Beta), and among its related pathways are Glycosphingolipid biosynthesis - globo series and Other glycan degradation. Affiliated tissues include bone, and related mouse phenotypes are hearing/vestibular/ear and renal/urinary system.

Disease Ontology:11 A lysosomal storage disease that has material basis in deficiency of the beta-a-manosidase enzyme resulting in the disruption of n-linked glycoprotein oligosaccharide catabolism.

Genetics Home Reference:24 Beta-mannosidosis is a rare inherited disorder affecting the way certain sugar molecules are processed in the body.

OMIM:50 Beta-mannosidosis is an autosomal recessive lysosomal storage disease of glycoprotein catabolism caused by a deficiency... (248510) more...
