Mucopolysaccharidosis type IX (MPS IX, Natowicz syndrome, Hyaluronidase deficiency, MIM:601492) is a rare lysosomal storage disease characterized by high hyaluronan (HA) concentration in the serum resulting from deficiency in hyaluronidase 1 (HYAL1, MIM:607071) which normally hydrolyses 1-4 linkages between N-acetylglucosamine (GlcNAc) and D-glucuronate (GlcA) residues. Symptoms of MPS IX are periodically painful soft tissue masses around the joints, acquired short stature and erosion of the hip joint, although joint movement and intelligence are normal (Natowicz et al. 1996, Triggs-Raine et al. 1999).
