Definition (MEDLINEPLUS)

Amyloidosis occurs when abnormal proteins called amyloids build up and form deposits. The deposits can collect in organs such as the kidney and heart. This can cause the organs to become stiff and unable to work the way they should.

There are three main types of amyloidosis:

  • Primary - with no known cause
  • Secondary - caused by another disease, including some types of cancer
  • Familial - passed down through genes

Symptoms can vary, depending upon which organs are affected. Treatment depends on the type of amyloidosis you have. The goal is to help with symptoms and limit the production of proteins. If another disease is the cause, it needs to be treated.

Definition (NCI_NCI-GLOSS) A group of diseases in which protein builds up in certain organs (localized amyloidosis) or throughout the body (systemic amyloidosis). Amyloidosis may be either primary (with no known cause), secondary (caused by another disease, including some types of cancer, such as multiple myeloma), or hereditary (passed down from parents to children). Many organs are affected by amyloidosis. The organs affected may depend on whether the amyloidosis is the primary, secondary, or hereditary form.
Definition (NCI_CDISC) A disorder characterized by the localized or diffuse accumulation of amyloid protein in various anatomic sites. It may be primary, due to clonal plasma cell proliferations; secondary, due to long standing infections, chronic inflammatory disorders, or malignancies; or familial. It may affect the nerves, skin, tongue, joints, heart, liver, spleen, kidneys and adrenal glands.

Definition (CSP) any disease manifested by the pathogenic accumulation of amyloid in organs and tissues.
Definition (MSH) A group of sporadic, familial and/or inherited, degenerative, and infectious disease processes, linked by the common theme of abnormal protein folding and deposition of AMYLOID. As the amyloid deposits enlarge they displace normal tissue structures, causing disruption of function. Various signs and symptoms depend on the location and size of the deposits.
