CARNITINE PALMITOYLTRANSFERASE DEFICIENCY IN A COLLEGE ATHLETE - A CASE-REPORT AND LITERATURE-REVIEW

Type II carnitine palmitoyltransferase deficiency is the most common cause of exercise-induced rhabdomyolysis, myoglobinuria, and proximal muscle weakness and pain in young adults. A lack of this enzyme impairs mitochondrial oxidation of long-chain fatty acids and can lead to rhabdomyolysis, myoglobinuria, and renal failure. Carnitine palmitoyltransferase deficiency, unusual but not rare, is often detected by finding elevated creatine phosphokinase level in a routine blood chemistry panel. A case of carnitine palmitoyltransferase deficiency in a college athlete is presented, and the disorder is compared with defective myophosphorylation in McArdle's disease, the next most frequent cause of similar symptoms.
