Mucolipidosis type 3 (Q91326)

Mucolipidosis III (MLIII) or pseudo-Hurler-polydystrophy is an inborn error of metabolism clinically similar to Scheie's or Hurler-Scheie's mucopolysaccharidoses. Clinical manifestations include joint stiffness leading to the diagnosis during childhood, dysostosis multiplex and a less severe facial dysmorphism. Intelligence may be normal but most children have hearing difficulties. Corneal clouding appears as the disorder progresses.
