Abstract Two brothers with a recently described inborn error of metabolism characterized by glyceroluria, hyperglycerolemia, and generalized glycerol kinase deficincy had moderate psychomotor reatradation, spasticity, growth failure, a nonspecific myopathy, osteoporosis, and adrenal insufficiency. Glycerol kinase activity in leukocytes and cultured fibroblasts was less thaan 5% of control values. Heptic and renal tissue obtained at autopsy in one patient had similarly low enzyme activity. Thus the deficiency of glycerol kinase in these patients appears to be generalized and heritable, though the relationship of the clinical phenotype to enzymatic deect is not yet established.
