Inherited metabolic disease in laboratory animals: a review

Abstract Research on the screening for and study of animal models of inherited metabolic disease is reviewed. It is emphasized that an animal model, to be of value, must be an inherited deficiency of the same enzyme as the one deficient in the human syndrome. If this criterion is adhered to there is a remarkable identity in aetiology between animal and man. Specific examples of inherited metabolic disease in laboratory animals are described for: amino acid metabolism, lysosomal storage diseases, carbohydrate metabolism, transport disorders and trace element metabolism; the mutants found in mice being the easiest to manipulate biochemically and genetically. There is still a lack of adequate screening programmes for animal homologues of the more serious human inborn errors (such as lysosomal storage diseases) where laboratory studies could provide significant advances in therapy.
