Abstract
All reported cases of 2,8-dihydroxyadenine (DHA) lithiasis have been due to functional homozygous deficiency of adenine phosphoribosyltransferase (APRT). Here we describe the first case of DHA lithiasis in a patient who has functional APRT activity in cultured lymphoblasts. The patient is heterozygous for Japanese-type (type II) APRT deficiency as demonstrated by starch-gel electrophoresis and DNA sequence analysis. We also demonstrate the use of starch-gel electrophoresis for differentiation between the type II mutant enzyme and the wild-type enzyme.Entities:
