Congenital Disorder

beta-Mannosidosis

An inborn error of metabolism marked by a defect in the lysosomal isoform of BETA-MANNOSIDASE that results in lysosomal accumulation of mannose-rich intermediate metabolites containing 1,4-beta linkages. The human disease occurs through autosomal recessive inheritance and manifests in the form of a variety of symptoms that depend upon the type of gene mutation.
