Loss of N-acetylglucosamine-1-phosphotransferase gamma subunit due to intronic mutation in GNPTG causes mucolipidosis type III gamma: Implications for molecular and cellular diagnostics.

Abstract excerpt

Mucolipidosis type III gamma (MLIII, pseudo-Hurler polydystrophy) is a rare autosomal recessive disorder where the activity of the multimeric GlcNAc-1-phosphotransferase is reduced and formation of the mannose 6-phosphate (M6P) recognition marker on lysosomal enzymes is impaired. In this disease, the targeting of lysosomal enzymes is affected resulting in their hypersecretion, and an intracellular deficiency of...
