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 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.
