Clinical and Molecular Description of PKD1 and PKD2 Mutation Negative Carriers in ADPKD (GeneQuest)

The aim of this study is to identify families with ADPKD , characterize the phenotype and screen for mutations in known genes (PKD1 and PKD2, and then HNF1b and UMOD in PKD1 PKD2 negative carriers).

Genome wide analysis will be performed in families without mutations identified.

Observational:

Blood collection

Participant information:

  • Both affected and non-affected relatives of PKD1 and PKD2 negative ADPKD patients will be recruited
  • DNA samples will be collected

Inclusion criteria for the proband:

  • Patients with a diagnosis of ADPKD
  • Written informed consent
  • Affiliated or benefiting from a national insurance

Exclusion criteria for the proband:

  • Subjects unable to provide written informed consent
  • Previous Molecular analysis of PKD1 and PKD2 genes with identification of the pathogenic mutation

Inclusion criteria of the relatives (affected or non affected):

  • Relatives with a diagnosis of ADPKD
  • Relatives over age 30 for whom the diagnosis of ADPKD has been discarded (non ADPKD relatives) with renal ultrasonography performed after age 30
  • Written informed consent; affiliated or benefiting from a national insurance

Exclusion criteria for the relatives:

  • Subjects unable to provide written informed consent
  • Age under 30 for the “non-affected” relatives
