AL amyloidosis

Saturday 28 September 2019


Definition : Amyloid light-chain (AL) amyloidosis, also known as primary amyloidosis, is the most common form of systemic amyloidosis in the US.

The disease is caused when a person’s antibody-producing cells do not function properly and produce abnormal protein fibers made of components of antibodies called light chains. These light chains come together to form amyloid deposits which can cause serious damage to different organs.

Abnormal light chains in urine are sometimes referred to as "Bence Jones protein".
