Deficient phosphorylation of mannose residues of mannan in fibroblasts of patients with mucolipidoses II and III. 1981

Y Ben-Yoseph, and L C Hahn, and C L DeFranco, and H L Nadler

Incorporation of 32P from [gamma 32P]ATP into mannan could not be detected in homogenates of cultivated skin fibroblasts from patients with mucolipidosis II, and accounted for only up to 10% of normal control activity in cell lysates from patients with mucolipidosis III. Parents of patients with mucolipidosis II demonstrated 60-70% of normal control activity. On high-voltage electrophoresis, the hydrolysed mannan from reactions performed with normal cells, over the pH range 5.5-7.5, yielded a radioactive band migrating with the same mobility as mannose 6-phosphate, whereas no such product could be demonstrated in fibroblasts of patients with mucolipidosis II.

D008358	Mannose	A hexose or fermentable monosaccharide and isomer of glucose from manna, the ash Fraxinus ornus and related plants. (From Grant & Hackh's Chemical Dictionary, 5th ed & Random House Unabridged Dictionary, 2d ed)	D-Mannose,Mannopyranose,Mannopyranoside,D Mannose
D009081	Mucolipidoses	A group of inherited metabolic diseases characterized by the accumulation of excessive amounts of acid mucopolysaccharides, sphingolipids, and/or glycolipids in visceral and mesenchymal cells. Abnormal amounts of sphingolipids or glycolipids are present in neural tissue. INTELLECTUAL DISABILITY and skeletal changes, most notably dysostosis multiplex, occur frequently.
