In this disease, the targeting of lysosomal enzymes is affected resulting in their hypersecretion, and an intracellular deficiency of multiple hydrolases. We report the biochemical and molecular diagnosis of MLIII in three siblings, aged 17, 15, and 14 years, who presented with joint pain and progressive joint stiffness. In addition to missorting of newly synthesized lysosomal protease cathepsin D, there were low levels of M6P-containing proteins in cell extracts and media of cultured fibroblasts of the Patients. Direct sequencing identified a novel homozygous mutation in intron 7, IVS7-10G>A, of the GNPTG gene, which encodes the gamma-subunit of the GlcNAc-1-phosphotransferase. This mutation created a cryptic 3'-splice site resulting in a frameshift and premature translational termination (p.V176GfsX18). The GNPTG mRNA levels were markedly reduced in Patients' fibroblasts indicating that the intronic mutation mediates mRNA decay, which was confirmed by absence of the gamma-subunit protein. These data contribute to an efficient diagnostic strategy to identify Patients with MLIII gamma and characterize their biochemical defect in fibroblasts."xsd:string |
