    Abstract:
    Autosomal dominant polycystic kidney disease (ADPKD) exhibits a genetically heterogeneous transmission involving at least three different genes. PKD1 gene linked mutations are responsible for the disease in about 85% of ADPKD cases. The search for mutations is a very important step in understanding the molecular mechanisms underlying ADPKD. We undertook this study using denaturing gradient gel electrophoresis (DGGE), after a stage of long range PCR, to scan for mutations in the duplicated region of the PKD1 gene in French ADPKD families. This allowed us to identify eight novel mutations and several polymorphisms: among the mutations, three are nonsense mutations, two are deletions in the coding sequence leading to frameshift mutations, one is a splice mutation and two are highly probable missense mutations. In this paper, we also provide a review of the mutations reported so far which are widespread throughout the gene. Although no clear hot spot for mutation is apparent, we will focus on some clustering observed.
