ANIMAL & CELL MODELS

glycerol kinase-deficient mice, mutant male mice appeared normal at birth, but exhibited postnatal growth retardation, altered fat metabolism with profound hyperglycerolemia and elevated free fatty acids, autonomous glucocorticoid synthesis, and death by 3 to 4 days of age whereas heterozygous females were healthy and biochemically normal
