Primary Outcome Measures:
  • To determine which genetic mutations are the cause of a more severe disease, in Dent Disease. [ Time Frame: 4 years ] [ Designated as safety issue: No ]

Estimated Enrollment: 602
Study Start Date: August 2012
Study Completion Date: September 2015
Primary Completion Date: September 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Genetic Analysis
Genetic Analysis
Genetic: Genetic Analysis

Detailed Description:

During this study visit, the investigator will draw one tube, about two teaspoonfuls (1 to 1 ½ teaspoons for children), of blood from your arm to obtain white blood cells. These white blood cells will be used as a source of DNA for genetic testing. We will use the isolated DNA to try to identify the gene that is defective in Dent Disease by comparing it with the structure of genes in normal individuals, patients with Dent Disease, and family members for Dent Disease.


Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
