Medical term:
mannosidosis
mannosidosis
[man″o-sĭ-do´sis]an inborn error of metabolism, thought to be an autosomal recessive trait, marked by a defect in alpha-mannosidase activity, resulting in lysosomal accumulation of mannose-rich substrates. Clinically, there are coarse features, upper respiratory congestion and infections, profound mental retardation, hepatosplenomegaly, cataracts, radiographic signs of defective ossification, and a gibbus deformity (hump). A much milder form also occurs.

mannosidosis
(măn′ə-sĭ-dō′sĭs)n.
1. An inherited lysosomal storage disease (alpha-mannosidosis) characterized by the accumulation of mannose-containing oligosaccharides in the tissues, resulting in symptoms of varying severity that include intellectual disability, enlarged liver and spleen, facial dysmorphism, skeletal abnormalities, immune deficiency, and hearing loss.
2. An inherited lysosomal storage disease (beta-mannosidosis) characterized by the accumulation of mannose-containing disaccharides in the tissues, resulting in intellectual disability, hearing loss, and often angiokeratomas.

mannosidosis
An autosomal recessive lysosomal storage disease similar to Hurler's disease, caused by a deficiency of the enzyme alpha mannosidase. There are two types; Type 1leads to an early death from severe systemic disturbances. Type II is less severe.Collins Dictionary of Medicine © Robert M. Youngson 2004, 2005
