IgA Nephropathy Facts
What is IgA Nephropathy?
IgA Nephropathy (IgAN) is a rare, 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.
How is IgA Nephropathy Diagnosed?
The first sign of IgAN is often blood in the urine. Should this occur, you should immediately consult your doctor.
How is IgA Nephropathy Treated?
There is no current cure for IgAN and that is why the IgA Nephropathy Foundation was founded.

What is IgA Nephropathy and How Does It Affect Your Kidneys?
IgAN occurs when abnormal antibody immunoglobulin A’s (IgA) are produced. The exact reason why Abnormal IgA’s are produced is unclear, but genetic factors likely play an important role. The body produces other antibodies (IgG) to attack the IgA antibodies that it no longer recognizes as ‘self’.
The IgG antibodies form a complex with the abnormal IgA antibodies and this complex often gets trapped at sites of filtration, specifically the kidneys. As a result, the body’s immune system attacks the abnormal IgA antibodies in the kidney, and affects the kidney’s ability to filter the wastes from your blood and produce healthy urine.
