There were reduced levels of mutant mRNA and Western blot analysis showed lack of the GNPTG protein, consistent with nonsense-mediated mRNA decay. The patients presented at about 7 years of age with progressive joint pain and stiffness, especially affecting the fingers, hip, and spine. All had myopia, but hearing and intelligence were normal. The 2 sisters had short stature, but their brother had normal height. Physical examination of all 3 sibs as teenagers showed short neck, hyperlordosis of the spine, short trunks, genu valgum, flat feet, and reduced joint mobility and contractures of the shoulders, spine, and fingers. Cultured fibroblasts derived from the brother showed reduced activities (30 to 50%) of lysosomal enzymes compared to controls. Radiolabeling of the lysosomal enzyme cathepsin D showed that patient fibroblasts had decreased levels of newly synthesized protein, and that most (70%) of the newly synthesized protein was missorted into the medium and not targeted to lysosomes. There were also low levels of M6P-containing proteins in fibroblasts extracts. <a href="https://pubmed.ncbi.nlm.nih.gov/?cmd=link&linkname=pubmed_pubmed&from_uid=20034096" target="_blank" onclick="gtag('event', 'mim_outbound', {'name': 'PubMed Related', 'domain': 'pubmed.ncbi.nlm.nih.gov'})"><span class="glyphicon glyphicon-plus-sign mim-tip-hint" title="Click this 'reference-plus' icon to see articles related to this paragraph in PubMed."></span></a></p>

<span class="mim-text-font">
<p>UDP-N-acetylglucosamine:lysosomal-enzyme N-acetylglucosamine-1-phosphotransferase (GlcNAc-phosphotransferase; EC 2.7.8.17) catalyzes the initial step in the synthesis of the mannose 6-phosphate (M6P) determinant required for efficient intracellular targeting of newly synthesized lysosomal hydrolases to the lysosome. GlcNAc-phosphotransferase is an alpha-2/beta-2/gamma-2 hexameric complex, the enzyme product of 2 genes: the gamma subunit is encoded by the GNPTG gene on chromosome 16, and the alpha and beta subunits are encoded by the GNPTAB gene (607840) on chromosome 12.</p>

<strong>Cloning and Expression</strong>

<span class="mim-text-font">
<p>Bao et al. (1996, 1996) determined that bovine GlcNAc-phosphotransferase is a 54-kD alpha-2/beta-2/gamma-2 hexameric complex. By EST database searching with the bovine GlcNAc-phosphotransferase gamma subunit as query, Raas-Rothschild et al. (2000) identified a partial clone of the human counterpart. They cloned a full-length GNPTAG cDNA by PCR, using a human brain cDNA library. The deduced mature GNPTAG protein has 281 amino acids and a molecular mass of 31 kD. It contains 2 N-glycosylation sites. Northern blot analysis detected a single 1.3-kb transcript in all 8 tissues examined. Additional transcripts up to 7.5 kb were found in lung. </p>

<p><strong><em>Mucolipidosis III Gamma</em></strong></p><p>
By sequence analysis of the GNPTAG in patients from 3 families with mucolipidosis IIIC (252605), Raas-Rothschild et al. (2000) identified a frameshift mutation that segregated with the disease (607838.0001). </p><p>In 10 patients from 7 families with mucolipidosis IIIC, Persichetti et al. (2009) identified 6 novel mutations in the GNPTG gene (see, e.g., 607838.0002-607838.0006). </p><p>In a Portuguese patient with mucolipidosis IIIC, Encarnacao et al. (2009) identified compound heterozygosity for 2 mutations in the GNPTG gene (607838.0007 and 607838.0008). Both the GNPTG and GNPTAB mRNA transcripts were significantly decreased (10- and 2.4-fold, respectively) compared to controls. The patient had a relatively mild phenotype with onset at age 10 years, no psychomotor retardation, and survival into adulthood. Encarnacao et al. (2009) suggested that the relatively mild phenotype could probably be explained by the fact that the gamma subunit does not contribute to the catalytic function of the enzyme. </p><p><strong><em>Associations Pending Confirmation</em></strong></p><p>

<p>In 3 Afghan sibs with mucolipidosis III gamma (252605), Pohl et al. (2010) identified a homozygous G-to-A transition in intron 7 of the GNPTG gene, resulting in a activation of a cryptic 3-prime splice site, frameshift, and premature termination. There were reduced levels of mutant mRNA and Western blot analysis showed lack of the GNPTG protein, consistent with nonsense-mediated mRNA decay. The patients presented at about 7 years of age with progressive joint pain and stiffness, especially affecting the fingers, hip, and spine. All had myopia, but hearing and intelligence were normal. The 2 sisters had short stature, but their brother had normal height. Physical examination of all 3 sibs as teenagers showed short neck, hyperlordosis of the spine, short trunks, genu valgum, flat feet, and reduced joint mobility and contractures of the shoulders, spine, and fingers. Cultured fibroblasts derived from the brother showed reduced activities (30 to 50%) of lysosomal enzymes compared to controls. Radiolabeling of the lysosomal enzyme cathepsin D showed that patient fibroblasts had decreased levels of newly synthesized protein, and that most (70%) of the newly synthesized protein was missorted into the medium and not targeted to lysosomes. There were also low levels of M6P-containing proteins in fibroblasts extracts. </p>
