Glycerol metabolism disorders (see the table Glycerol Metabolism Disorders ) are among the fatty acid and glycerol metabolism disorders Overview of Fatty Acid and Glycerol Metabolism Disorders Fatty acids are the preferred energy source for the heart and an important energy source for skeletal muscle during prolonged exertion. Also, during fasting, the bulk of the body’s energy needs... read more .

Glycerol kinase deficiency is X-linked X-Linked Recessive Genetic disorders determined by a single gene (Mendelian disorders) are easiest to analyze and the most well understood. If expression of a trait requires only one copy of a gene (one allele)... read more ; many patients with this deficiency also have a chromosomal deletion that extends beyond the glycerol kinase gene into the contiguous gene region, which contains the genes for congenital adrenal hypoplasia and Duchenne muscular dystrophy. Thus, patients with glycerol kinase deficiency may have one or more of these disease entities.
Symptoms of glycerol metabolism disorders begin at any age and are usually accompanied by acidosis, hypoglycemia, and elevated blood and urine levels of glycerol.
Diagnosis of glycerol metabolism disorders is by detecting an elevated level of glycerol in serum and urine and is confirmed by DNA analysis. (Also see testing for suspected inherited disorders of metabolism Initial testing Most inherited disorders of metabolism (inborn errors of metabolism) are rare, and therefore their diagnosis requires a high index of suspicion.

Glycerol metabolism disorder treatment is with a low-fat diet, but glucocorticoid replacement is critical for patients with adrenal hypoplasia.
