Glycerol Kinase Deficiency

Glycerol Kinase Deficiency (Hyperglycerolemia; Glyceroluria; GK Deficiency; GKD) is a rare metabolic disease caused by a deficiency in the GK gene which codes for glycerol kinase. A deficiency in this enzyme results in accumulation of glycerol in urine and serum. Symptoms include cryptorchism, trabismus, myopathy, lethargy, and vomiting. Treatment includes corticosteroids and acute glucose infusion.
