Autosomal dominant tubulointerstitial kidney disease-UMOD

Autosomal dominant tubulointerstitial kidney disease-UMOD (ADTKD-UMOD) is part of a group of disorders (collectively called autosomal dominant tubulointerstitial kidney disease or ADTKD) that cause a slow loss of kidney function. In people with ADTKD-UMOD, the signs and symptoms of kidney disease often begin in adolescence or early adulthood. Over time, the kidneys become less able to filter fluids and waste products from the body. People with ADTKD-UMOD eventually develop kidney failure, which requires either dialysis to remove waste from the blood or a kidney transplant. The age at which people with ADTKD-UMOD develop kidney failure can vary, though the average age is approximately 45 years. 

People with ADTKD-UMOD typically develop high levels of a waste product called uric acid in their blood. Normally, the kidneys transfer uric acid from the blood into urine, which then removes it from the body. People with ADTKD-UMOD are unable to remove uric acid from the blood effectively. In about 50 percent of people with ADTKD-UMOD, uric acid builds up in the joints and causes a form of arthritis called gout, typically in late adolescence or early adulthood. Gout is characterized by a sudden onset of severe joint pain and redness, often starting in the big toe. Untreated episodes of gout typically worsen over time.
