Scientists find genetic pathway that could lead to drugs for kidney disease

that eventually debilitate the kidney, causing kidney failure in half of all patients by the time they reach age 50. Currently no treatment exists to prevent or slow cyst formation, and most ADPKD patients require kidney transplants or life-long dia...
