mucolipidosis[mu″ko-lip″ĭ-do´sis] (pl. mucolipido´ses)
any of a group of genetic disorders in which both glycosaminoglycans (GAGs) and 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.
mucolipidosis somewhat like a mild form of Hurler syndrome with coarse facial features, macular cherry red spots, myoclonus epilepsy, mild dysostosis multiplex, and moderate mental retardation due to neuraminidase deficiency; autosomal recessive inheritance caused by mutation in the neuraminidase gene (NEU) on 6p.

Mucolipidosis somewhat like a mild form of Hurler syndrome with coarse facial features, macular cherry red spots, myoclonus epilepsy, mild dysostosis multiplex, and moderate mental retardation due to neuraminidase deficiency.

Lysosomal storage disease resembling mild form of Hurler syndrome with coarse facial features, macular cherry red spots, and other findings.
