Glycerol and glycerol kinase activity analyses are usually not offered by routine general medical laboratories. To diagnose<unk> , blood and urine can be tested for the amounts of glycerol present. There are three clinical forms of GKD: infantile, juvenile, and adult. The infantile form is associated with severe developmental delay and results in a syndrome with Xp21 gene deletion with congenital adrenal hypoplasia and/or Duchenne muscular dystrophy. The infantile diagnosis is made by measuring plasma glycerol and is characterized by glycerol levels between 1.8 and 8.0 mmol/L and glyceroluria more than 360 mmol/24h. To confirm the diagnosis, genetic testing of the Xp21 gene is definitive. Children with GKD have severe hypoglycemic episodes and profound metabolic acidosis, or are completely symptom free. Individuals who are unable to form glucose from the glycerol released during triglyceride catabolism also the hypoglycemic episodes often disappear during adolescence. Patients with the juvenile and adult forms often have no symptoms and are diagnosed fortuitously when a medical professional tests for another medical condition. The juvenile form is an uncommon form characterized by Reye syndrome-like clinical manifestations including episodic vomiting, acidemia, and disorders of consciousness.
