Question

what is responsible for the deficiency in I cell disease patients in which the lysosomal enzymes do not carry the normal mannose phosphate residues that target them to lysosomes? what is responsible for the deficiency in I cell disease patients in which the lysosomal enzymes do not carry the normal mannose phosphate residues that target them to lysosomes? what is responsible for the deficiency in I cell disease patients in which the lysosomal enzymes do not carry the normal mannose phosphate residues that target them to lysosomes?
