pseudo-Hurler polydystrophy mucolipidosis III.

mu·co·lip·i·do·sis III

[MIM*252600, MIM*252605]
mucolipidosis with mild Hurlerlike symptoms, restricted joint mobility, short stature, mild mental retardation, and dysplastic skeletal changes, especially of the hip; aortic and mitral valve disease is often present; associated with a deficiency of N-acetyl-α-glucosaminidase or other enzyme deficiencies such as lysosomal enzyme N-acetylglucosaminyl-1-phosphotransferase in mutant fibroblasts; lacks the ability to recognize lysosomal enzymes and specific substrates for phosphorylation; autosomal recessive inheritance.

pseudo-Hurler polydystrophy

a disorder similar to but milder than I cell disease and thought to result from the same enzyme deficiency but to a lesser extent.

I-Cell disease (mucolipidosis II, McKusick 252500) and a clinically milder, form pseudo-Hurler polydystrophy (mucolipidosis III, McKusick 252600), are autosomal, recessively inherited lysosomal storage diseases in which the transport of newly synthesized lysosomal enzymes into lysosomes is affected (6).
