  Mucopolysaccharidoses Fact Sheet: National Institute of Neurological Disorders and Stroke (NINDS)
The mucopolysaccharidoses are a group of inherited metabolic diseases caused by the absence or malfunctioning of certain enzymes needed to break down molecules called glycosaminoglycans - long chains of sugar carbohydrates in each of our cells that help build bone, cartilage, tendons, corneas, skin, and connective tissue.
Persons with mucolipidosis may share some of the clinical features associated with the mucopolysaccharidoses (certain facial features, bony structure abnormalities, and damage to the brain), and increased amounts of the enzymes needed to break down the lipids are found in the blood.
The disorder is caused by deficiency of the enzyme beta-glucuronidase.

The mucopolysaccharidoses are a group of inherited disorders of lysosomal storage characterized by deposits of certain complex carbohydrates (mucopolysaccharides) in many tissues and organs of the body (i.e., eyes, skeleton, arteries, joints, ears, skin, and/or teeth).
Sialidosis (mucolipidosis I) is a very rare inherited metabolic disorder characterized by a deficiency of the enzyme alpha-neuraminidase and belongs to a group of diseases known as lysosomal storage disorders.

Mucopolysaccharidoses: Group of diseases affecting metabolism of mucopolysaccharides.
Mucopolysaccharidoses: Mucopolysaccharidoses consist of a group of inherited metabolic disorders caused by a deficiency of the specific lysosomal enzymes needed to break down mucopolysaccharides.
When mutations occur in the genes for the enzymes involved in the normal turnover of mucopolysaccharides, excess amounts of them are stored in the body, causing progressive damage and, in most cases, eventual death.

 Mucopolysaccharidoses Information Page: National Institute of Neurological Disorders and Stroke (NINDS)
The mucopolysaccharidoses are a group of inherited diseases in which a defective or missing enzyme causes large amounts of complex sugar molecules to accumulate in harmful amounts in the body's cells and tissues.
Currently, scientists are working to identify the genes associated with the mucopolysaccharidoses syndromes and plan to test new therapies in animal models and in humans.
Research funded by the Institute has shown that viral-delivered gene therapy in animal models of the mucopolysaccharidoses can stop the buildup of storage materials in brain cells and improve learning and memory.

 Lysosomal diseases-General principles
The most common among them are the mucopolysaccharidoses (MPS), which affect one in every 100,000 to 200,000 liveborn infants.
The mucopolysaccharidoses and glycoproteinoses affect neurons but have also severe skeletal and visceral manifestations which constitute the mucopolysaccharidosis phenotype.
In general, the cells that are most severely affected by LSDs are neurons, because they process large amounts of gangliosides and once lost they cannot be replaced, and histiocytes, because their main function is lysosomal degradation, and they decompensate if their lysosomal enzymes are deficient.

Lysosomal storage diseases (LSDs) describe a heritable group of heterogenous human disorders characterized by the accumulation of undigested macromolecules intralysosomally, resulting in an increase in the size and number of these organelles.
LSDs are generally classified by the accumulated substrate and they include sphingolipidoses, glycoproteinoses, mucolipidoses, mucopolysaccharidoses (MPSs), and others.
The concept of LSD has expanded to include deficiencies in lysosomal enzymes, in the noncatalytic lysosomal proteins, and more general abnormalities in lysosomal function all occurring within the lysosome.
