Light Chain Amyloidosis is a rare disease caused by the buildup of abnormal proteins called amyloid in various tissues and organs. These proteins are produced by a type of blood cell known as plasma cells. When these cells malfunction, they create excess light chains, which can misfold and accumulate, leading to damage in organs such as the heart, kidneys, and liver. Symptoms of Light Chain Amyloidosis can vary widely but often include fatigue, swelling, and organ dysfunction. Diagnosis typically involves blood tests, urine tests, and imaging studies to assess the extent of amyloid deposits. Early detection and treatment are crucial for managing the condition effectively.
