From OMIMAutosomal dominant tubulointerstitial kidney disease-1 (ADTKD1) is an adult-onset slowly progressive renal disease characterized by elevated serum uric acid (hyperuricemia) due to low fractional excretion of uric acid, defective urinary concentrating ability, 'bland' urinary sediment, and progression to end-stage renal failure. Some patients may develop gouty arthritis, arterial hypertension, polydipsia/polyuria, or mild proteinuria. The onset of symptoms is usually in the third or fourth decade, although earlier and later onset have been reported. Renal ultrasound may show small or hyperechogenic kidneys. Renal biopsy shows variable abnormalities, including tubular atrophy, interstitial fibrosis, microcystic dilatation of the tubules, thickening of tubular basement membranes, medullary cysts, and secondary glomerulosclerotic or glomerulocystic changes with abnormal glomerular tufting. The median age at onset of end-stage renal disease (ESRD) is 56 years (range 50-65). There is significant inter- and intrafamilial variability, as well as incomplete penetrance, which hampers diagnosis (summary by Hart et al., 2002, Ayasreh et al., 2018, and Devuyst et al., 2019).
Genetic Heterogeneity of Autosomal Dominant Tubulointerstitial Kidney Disease
ADTKD2 (174000) is caused by mutation in the MUC1 gene (158340) on chromosome 1q22; ADTKD3 (137920) is caused by mutation in the HNF1B gene (189907) on chromosome 17q12; ADTKD4 (613092) is caused by mutation in the renin gene (REN; 179820) on chromosome 1q32; and ADTKD5 (617056) is caused by mutation in the SEC61A1 gene (609213) on chromosome 3q21.
See 614227 for a possibly distinct form of ADTKD tentatively mapped to chromosome 2p22.1-p21.
http://www.omim.org/entry/162000 From MedlinePlus GeneticsUromodulin-associated kidney disease is an inherited condition that affects the kidneys. The signs and symptoms of this condition vary, even among members of the same family.
Many individuals with uromodulin-associated kidney disease develop high blood levels of a waste product called uric acid. Normally, the kidneys remove uric acid from the blood and transfer it to urine. In this condition, the kidneys are unable to remove uric acid from the blood effectively. A buildup of uric acid can cause gout, which is a form of arthritis resulting from uric acid crystals in the joints. The signs and symptoms of gout may appear as early as a person's teens in uromodulin-associated kidney disease.
Uromodulin-associated kidney disease causes slowly progressive kidney disease, with the signs and symptoms usually beginning during the teenage years. The kidneys become less able to filter fluids and waste products from the body as this condition progresses, resulting in kidney failure. Individuals with uromodulin-associated kidney disease typically require either dialysis to remove wastes from the blood or a kidney transplant between the ages of 30 and 70. Occasionally, affected individuals are found to have small kidneys or kidney cysts (medullary cysts).
