  Purpose
The aim of this study is to identify families with hereditary chronic tubulointerstitial renal diseases , characterize the phenotype and screen for mutations in known genesis (UMOD, REN, TCF2, NPHP1). Genome wide analysis will be performed in families without mutations identified.

Condition Intervention
Nephritis, Interstitial Chronic Renal Failure Gout Renal Cysts Other: Blood and urine sample collections

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Screening
Official Title: Phenotypical and Genetic Characterization of Adult Hereditary Chronic Tubulointerstitial Renal Diseases

Further study details as provided by Assistance Publique - Hôpitaux de Paris:

Primary Outcome Measures:
  • Genotype of HTIN [ Time Frame: after 18 months ]
    Number of patients/families with mutations in known genes responsible for HTIN


Secondary Outcome Measures:
  • Uromodulin dosage in urine [ Time Frame: at 18 months ]

Enrollment: 225
Study Start Date: November 2010
Study Completion Date: July 2016
Primary Completion Date: February 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
HTIN
HTIN
Other: Blood and urine sample collections
phenotype and genotype analysis, biological analysis
Other Name: phenotype and genotype analysis, biological analysis

Detailed Description:
  • Inclusion of affected subjects with familial history of chronic renal failure, early gout ,renal cysts in several hospital in France
  • Characterization of the phenotype; dosage of the urinary uromodulin in all subjects
  • Collect DNA samples
  • Screen for UMO mutations first
  • Then for REN or TCF2 depending on the phenotype
  • Validate the use of the dosage of urinary uromodulin for the diagnosis of UMOD associated disease.
  • Identify new genes responsible for hereditary HTIN (Hereditary Tubulointerstitial Nephritis).
