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

March 23, 2021 updated by: University Hospital, Brest

Clinical and Molecular Description of PKD1 and PKD2 Mutation Negative Carriers in Autosomal Dominant Polycystic Kidney Disease (ADPKD): The GeneQuest Study

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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

  • Inclusion of ADPKD patients in 20 different centers of Nephrology in the Western part of France
  • Characterization of the Phenotype
  • Collect DNA sample
  • Analysis of PKD1 and PKD2 genes first
  • Analysis of HNFIb and UMOD for PKD1 and PKD2 negative patients
  • Recruitment of affected and non-affected relatives of PKD1 and PKD2 negative ADPKD patients
  • Identify new genes involved in ADPKD using exome sequencing in PKD1 and PKD2 negative pedigrees

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

16 years and older (ADULT, OLDER_ADULT, CHILD)

Accepts Healthy Volunteers
