Purine and pyrimidine metabolism defects

Adenine phosphoribosyl transferase deficiency (APRT)

Description

Adenine phosphoribosyltransferase (APRT) catalyzes the formation of AMP from adenine and phosphoribosylpyrophosphate. A deficiency of APRT can lead to accumulation of the insoluble purine 2,8-dihydroxyadenine and nephrolithiasis.
