Preferred Label : Mucolipidosis III gamma;

Description : Mucolipidosis type III gamma is an autosomal recessive disorder characterized clinically
by short stature, skeletal abnormalities, cardiomegaly, and developmental delay. The
disorder is caused by a defect in proper lysosomal enzyme phosphorylation and localization,
which results in accumulation of lysosomal substrates (summary by Raas-Rothschild
et al., 2000).;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the N-acetylglucosamine-1-phosphotransferase, gamma subunit
gene (GNPTG, 607838.0001);
Laboratory abnormalities : No mucopolysacchariduria; Decreased fibroblast arylsulfatase A; Increased serum beta-hexosaminidase; Increased serum alpha-mannosidase; Increased serum iduronate sulfatase; Increased serum arylsulfatase A.; Decreased fibroblast beta-hexosaminidase; Decreased fibroblast alpha-mannosidase; Decreased fibroblast iduronate sulfatase; Decreased N-acetylglucosamine-1-phosphotransferase (GlcNAc - phosphotransferase) using
lysosomal enzymes; Normal-to-slightly decreased GlcNAc phosphotransferase using artificial substrate
(e.g., alpha-methylmannoside);
