IgA Nephropathy (IgAN)<\/strong><\/h1>\n\n\n\n

IgA Nephropathy (IgAN) is a kidney disease in which Immunoglobulin A (IgA) builds up in the kidney. IgA is a protein in the blood. IgA is also part of the immune system. Excess IgA can cause inflammation in the kidney. Over time, this leads to scarring in the kidney tissue. The severity of kidney disease caused by IgAN varies from person to person. As IgAN progresses, it reduces the kidneys\u2019 ability to filter waste from the blood.<\/p>\n\n\n\n
