mucolipidosis IV

mucolipidosis

 [mu″ko-lip″ĭ-do´sis] (pl. mucolipido´ses) any of a group of genetic disorders in which both glycosaminoglycans" >glycosaminoglycans (GAGs) and lipids" >lipids accumulate in tissues, but without excess of GAG in the urine.mucolipidosis I sialidosis (type I).mucolipidosis II a rapidly progressing disease of young children, histologically characterized by abnormal fibroblasts containing a large number of dark inclusions which fill the central part of the cytoplasm except for the juxtanuclear zone (I-cells), and clinically by severe growth impairment, minimal hepatic enlargement, extreme mental and motor retardation, and clear corneas; inherited as an autosomal recessive trait, it is due to deficiency of multiple lysosomal hydrolases. Called also I-cell disease.mucolipidosis III a disorder similar to but milder than mucolipidosis II, and thought to be due to the same enzyme deficiency but to a lesser extent. Called also pseudo-Hurler polydystrophy.mucolipidosis IV a form marked by early corneal clouding, psychomotor retardation, and the presence of lysosomal storage bodies; thought to be transmitted as an autosomal recessive trait.

mu·co·lip·i·do·sis IV

[MIM*252650] psychomotor retardation with cloudy corneas and retinal degeneration, with inclusion cells in cultured fibroblasts; the pathogenesis is uncertain; autosomal recessive inheritance.

mucolipidosis IV

n. A type of mucolipidosis characterized by psychomotor delay, unsteady gait, corneal clouding, and retinal degeneration.
