Summaries for Mannosidosis, Beta

UniProtKB/Swiss-Prot : 66 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 mannosidosis and intracranial hypotension, and has symptoms including seizures, intellectual disability and hearing impairment. An important gene associated with Mannosidosis, Beta is MANBA (Mannosidase Beta), and among its related pathways/superpathways are MECP2 and Associated Rett Syndrome and Lysosome. The drug Krestin has been mentioned in the context of this disorder. Affiliated tissues include bone, and related phenotypes are behavior/neurological and cellular

Disease Ontology : 12 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 : 25 Beta-mannosidosis is a rare inherited disorder affecting the way certain sugar molecules are processed in the body.
