The disorder damages the tiny blood vessels in the kidneys, called glomeruli, that filter wastes.
At first, there are no symptoms. However, progressive destruction of the glomeruli leads to blood in the urine and may decrease the effectiveness of the kidney's filtering system. There is a progressive loss of kidney function and a buildup of fluids and waste products in the body.
