Medical Definition of Inclusion cell disease
1.
Mucolipidosis of early onset and with severe symptoms like those in Hurler's syndrome but with normal urinary mucopolysaccharides, vacuolated lymphocytes, and inclusion bodies in cultured fibroblasts (I-cells).
The lysosomes lack hydrolases but high concentrations of lysosomal enzymes are found in the extracellular fluids such as serum, spinal fluid, and urine.
It is associated with a deficiency of N-acetylglucosaminyl-1-phosphotransferase. The gene defect responsible probably prevents the addition of the lysosome recognition marker mannose 6 phosphate) to these enzymes so that they are not directed into the lysosomes but are released.
Inheritance: autosomal recessive.
Synonym: I-cell disease, inclusion cell disease.
