gly·co·ge·no·sis (glk-j-nss)

n.

Any of various inheritable diseases caused by enzyme deficiencies and characterized by the abnormal accumulation of glycogen in tissue. Also called dextrinosis, glycogen storage disease.

glycogenosis

pl. glycogenoses; any genetically determined disorder of glycogen metabolism, marked by abnormal storage of glycogen in the tissues of the body. See also glycogen storage disease.

bovine generalized glycogenosis

an inherited glycogen storage disease of Shorthorn and Brahman cattle resembling glycogenosis type II (Pompe's disease) of humans, caused by a deficiency of α-1,4-glucosidase. Widespread accumulation of glycogen occurs in the nervous system and muscles, leading to poor growth, incoordination, muscle weakness and eventually recumbency. There is also cardiomyopathy and often left-sided heart failure. Onset is at 2 to 3 months of age with death at 3 to 5 months. A late onset form with a short clinical course is described in 8 to 9 month old Brahman cattle.

glycogenosis type I

in humans, a deficiency of the hepatic enzyme glucose-6-phosphatase resulting in liver and kidney involvement, with hepatomegaly, hypoglycemia, hyperuricemia and gout. A similar condition has been observed in young dogs with hypoglycemia that does not respond to glucagon. Called also Gierke's disease or von Gierke's disease.

glycogenosis type II

see bovine generalized glycogenosis (above). Also reported in sheep, cats, dogs and quail. Called also Pompe's disease.

glycogenosis type III

an inherited deficiency of amylo-1,6-glucosidase causing neurological deterioration, hepatomegaly and retarded growth in German shepherd dogs from an early age. Called also Cori's disease, Forbes' disease, limit dextrinosis.

glycogenosis type IV

an inherited deficiency of glycogen branching enzyme activity resulting in storage of abnormal glycogen, especially in the liver and spleen. Reported in Norwegian forest cats. Called also Andersen disease, amylopectinosis.

glycogenosis type V

an inherited deficiency of myophosphorylase which results in muscle cramping with exercise. Reported in Charolais calves. Called also McArdle disease.

glycogenosis type VII

see phosphofructokinase 1 deficiency.
