Any genetic disorder that prevents nucleotide sugars, a type of activated sugar, nucleotide sugar from entering the compartments of the cell where it is needed for glycosylation. Since nucleotide sugars are a key class of activated sugars involved in the synthesis of glycolipids/glycoproteins, disorders of nucleotide sugar transport will negatively affect multiple glycosylation pathways.
Synonyms:
disorders of nucleotide sugar transport
