My name is Sean and I will be running the 2024 Marine Corps Marathon to raise money for The IgA Nephropathy Foundation. Earlier this year, my youngest son Joseph was diagnosed with 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. There are a number of treatments for the disease, but no cure. Please help me raise money for IgAN research and to assist other people who are afflicted with this disease.
