The inherited defects involving pyrimidine metabolism lead to nervous system, hematologic and mitochondrial disease. Purine Salvage Disorders. … Disorders resulting from the purine salvage pathway include: (1) hypoxanthine-guanine phosphoribosyltransferase (HPRT) deficiency, and (2) adenine phosphoribosyltransferase (APRT) deficiency. Disorders of Steroid Synthesis and Metabolism. Disorders of Golgi homeostasis form an emerging group of genetic defects. Hypoglycaemia can also be caused by disorders affecting the use of other fuels, such as those producing fatty acids and ketone bodies which are important alternative sources of energy. This is an inherited disorder which causes the excessive production of orotic acid. Clinical problems associated with nucleotide metabolism in humans are predominantly the result of abnormal catabolism of the purines. Inherited disorders of bilirubin metabolism result in hyperbilirubinemia. This occurs by the deficiency of orotatc phosphoribosyl transferase.
