[The molecular genetic analysis of polycystic kidney disease].
Autosomal dominant polycystic kidney disease (ADPKD) is one of common single gene disorders. The development of molecular genetic techniques has shown that mutant PKD1 gene assigned to ADPKD was closely linked to alpha-globin on the short arm of chromosome 16. This location was established when genetic linkage was found between ADPKD and a highly polymorphic region at the 3' end of the alpha-globin cluster (3' HVR). The discover of genetic linkage markers such as 3' HVR probe has provided a diagnostic test in presymptomatic stage. We performed this diagnostic test using DNA probes in 3 patients with ADPKD of one Japanese family. They also showed PKD1 gene linkage as previously described by Reeders et al. Linkage analysis of the PKD1 gene might be available to diagnostic test of ADPKD. DNA diagnosis of ADPKD however has to be performed carefully because of an ethical standpoint.
