Familial (hereditary) amyloidosis is a genetic form passed down in families that often affects nerves and kidneys. Secondary amyloidosis (AA) develops along with a chronic infectious or inflammatory disease, such as tuberculosis or rheumatoid arthritis.
Amyloidosis sometimes develops when a person has certain forms of cancer, such as multiple myeloma, Hodgkin's disease or familial Mediterranean fever (an intestinal disorder). It also sometimes occurs in people with kidney disease who have undergone dialysis for a long time.
