Description

Background: ADTKD is characterized by autosomal dominant inheritance and slowly progressive chronic kidney disease associated with a bland urinary sediment and normal ultrasound. Mutations in UMOD, MUC1, and REN are the most common casues of this disorder. MUC1 genetic testing cannot be done with standard Sanger sequencing and is not included in gene panels or whole exome sequencing. We are trying to increase awareness and diagnosis of this condition and enroll patients in a prospective observational study to learn about disease progression.
Clinical Trials: (1) Genetic diagnosis in ADTKD. We are able to perform genotyping for MUC1, UMOD, and REN at no cost to the participant. Testing is performed for individuals with a family history of kidney disease associated with a bland urinary sediment. Clinical testing is available for the MUC1 gene free of charge as well. (2) Prospective international observational study. Patients with genetically proven UMOD, MUC1, or REN mutations are invited to participate. Genotyping can be provided. A baseline collection of biomarkers is performed followed by serum creatinine determinations every 4-6 months. A patient survey is completed on-line every four months regarding medication use, diet, and blood pressure. Laboraory testing is free, and results are provided to patients. This study is a precursor to a future interventional study. (3) We are using advanced genetic and immunohistochemical techniques to diagnose individuals with inherited kidnye disease of unknown cause.
