NCIt definition : Human GNPTAB wild-type allele is located in the vicinity of 12q23.2 and is approximately
85 kb in length. This allele, which encodes N-acetylglucosamine-1-phosphotransferase
subunits alpha/beta protein, plays a role in the synthesis of mannose 6-phosphate
recognition markers on certain oligosaccharides of newly synthesized lysosomal enzymes.
Mutation of the gene is associated with inclusion-cell disease and mucolipidosis types
