Alternative titles and symbols : ADMCKD2; Familial juvenile hyperuricemic nephropathy; Gouty nephropathy, familial juvenile; FJHN; HNFJ1; Medullary cystic kidney disease 2, autosomal dominant; MCKD2; Glomerulocystic kidney disease with hyperuricemia and isosthenuria; Hyperuricemic nephropathy, familial juvenile, 1; Medullary cystic kidney disease 2;

Description : Familial juvenile hyperuricemic (gouty) nephropathy (HNFJ) is an autosomal dominant disorder characterized by elevated serum uric acid concentrations due to a low fractional excretion of uric acid, defective urinary concentrating ability, interstitial nephropathy, and progression to end-stage renal failure (summary by Piret et al., 2011). A form of medullary cystic kidney disease (MCKD2; 603860) is also caused by mutation in the UMOD gene, as is a form of glomerulocystic kidney disease (609886) with hyperuricemia and isosthenuria. - Genetic Heterogeneity of Familial Juvenile Hyperuricemic Nephropathy Familial juvenile hyperuricemic nephropathy-2 (HNFJ2; 613092) is caused by mutation in the renin gene (REN; 179820) on chromosome 1q32. HNFJ3 (614227) has been mapped to chromosome 2p22.1-p21. An atypical form of HNFJ, associated with renal cysts and diabetes, is caused by mutation in the HNF1B gene (189907) on chromosome 17q12.;

Inheritance : Autosomal dominant;

Molecular basis : Caused by mutation in the uromodulin gene (UMOD, 191845.0001);

Laboratory abnormalities : Decreased urinary excretion of uromodulin;

Prefixed ID : #162000;
