Mucopolysaccharidoses type IV A (Morquio syndrome): a case series of three siblings

Abstract

Mucopolysaccharidoses (MPS) are a family of inherited metabolic diseases that results from the deficiency of lysosomal enzymes involved in the degradation of the glycosaminoglycans (mucopolysaccharides). Despite the well-documented oral and dental findings of MPS type IV, there is not much literature documented about the incidence of this disorder among siblings in the same family. This report outlines the clinical and radiographic findings found in three siblings with Morquio syndrome.
