WHAT IS IGA NEPHROPATHY?
IgA Nephropathy (IgAN) is an autoimmune disease that attacks the kidneys. It affects how blood is filtered in the small blood vessels of the kidneys. IgAN occurs when an abnormal protein damages the filtering unit (glomerulus) inside the kidneys. It is estimated that 20-40% of the people who have IgAN will develop end-stage kidney disease, which means they will need dialysis or kidney transplantation to survive.
