Assisting in the diagnosis of Morquio A disease
Preferred test to rule out Mucopolysaccharidosis IVA, (MPS IVA, Morquio A syndrome). Not recommended for carrier detection.
Morquio A is an autosomal recessive mucopolysaccharidosis caused by reduced or absent N-acetylgalactosamine-6-sulfate sulfatase (GALNS) enzyme activity.
Although clinically similar, Morquio A is genetically and enzymatically distinct from Morquio B. Enzyme analysis is necessary to distinguish between the 2.
The test cannot be used to establish carrier status for Morquio A disease.
