What is the cause of Morquio syndrome?

What is the cause of Morquio syndrome?

Causes. Morquio syndrome is a genetic disorder, and it results from mutations of two specific genes: GALNS and GLB1. 2 Primarily, these are involved in the production of enzymes that digest larger sugar molecules called glycosaminoglycans (GAGs).

How long do you live with Morquio syndrome?

Unlike in several other MPS diseases, intellectual abilities are usually spared. Morquio syndrome includes mild, moderate, and severe forms. Although all forms are characterized by skeletal disease, individuals affected by milder cases may live over 70 years, while severe cases do not typically live beyond age 30.

How does Boston Children’s Hospital treat Morquio syndrome?

Morquio Syndrome – Causes, Symptoms, Treatment. This syndrome is caused by lack of continuity in the breaking up of sugar molecules due to absence of muco-polysaccharides. For this reason this disorder is medically called as Galactosamine 6 sulfatase deficiency and mucopolysaccharidosis.

How does Morquio syndrome affect the body?

Morquio syndrome is a problem that occurs when the body lacks or does not produce enough enzyme that will digest the long strands of sugar molecules. This would cause the sugar molecules to collect and harm the cells and tissues resulting in various skeletal and physical problems, hearing loss, vision problems and heart abnormalities.

Who was first described Morquio syndrome?

Morquio’s syndrome is an autosomal recessive mucopolysaccharide storage disease which is characterized by the inability to metabolize keratin sulphate. It was first described in 1929 by Luis Morquio in Montevideo, Uruguay . He observed the disorder in four siblings in a family of Swedish extraction and recognized the occurrence of corneal clouding, aortic valve disease and the urinary excretion of keratan sulfate.

What is the history of Morquio syndrome?

Morquio’s syndrome is an autosomal recessive lysosomal storage disorder caused by deficiency of either the enzyme N-acetyl-galactosamine-6-sulfate sulfatase (Morquio A) or enzyme beta-galactosidase (Morquio B). It was first described in 1929 by Luis Morquio, a paediatrician from Uruguay, and James Brailsford, a radiologist from the UK.
