title: Disorders associated with purine and pyrimidine metabolism.
abstract: There has been an explosion of knowledge in disorders of purine and pyrimidine metabolism during the last 20 years. During this time, more than 10 diseases have been discovered and their metabolic bases studied. Hyperuricemia and gout remain the most common clinical disorder. Rarely these disorders are explainable by an inherited enzyme abnormally, such as hypoxanthine-guanine phosphoribosyltransferase deficiency, phosphoribosyl-pyrophosphate synthetase deficiency, or glucose-6-phosphatase deficiency. The description of immunodeficiency syndromes in association with purine enzyme deficiency has led to a novel area of investigation encompassing the biochemical basis for immune function. Although less information is available concerning the other diseases associated with renal calculi, myopathy, anemia, and central nervous system dysfunction, further research will elucidate important metabolic relationships. These will no doubt expand our understanding of the pathogenesis of these disorders and provide innovative therapeutic approaches.
