Abstract |
We have applied an established technique, the polymerase chain reaction (PCR) with LightCycler technology, to a single disease with well-defined mutations. This assay produces results within only 30 min by combining PCR and fluorescence detection in one tube without electrophoretic band detection. In this study, we found 2,8-dihydroxyadenine (DHA) lithiasis in Japanese patients who were heterozygous for Japanese-type (type II) adenine phosphoribosyltransferase ( APRT) deficiency (APRT*J). These patients, from a family with 2,8-DHA lithiasis, had a heterozygous mutation in the J region of the APRT gene. We demonstrated that the present system, using LightCycler technology, was simple, rapid, and reliable for detecting known mutations, and capable of identifying heterozygous and homozygous mutations in this family with APRT deficiency.
