Amyloidosis

Amyloidosis is the name for a group of rare, serious conditions caused by a build-up of an abnormal protein called amyloid in organs and tissues throughout the body.

The build-up of amyloid proteins (deposits) can make it difficult for the organs and tissues to work properly. Without treatment, this can lead to organ failure.

This page focuses on AL amyloidosis (previously known as primary amyloidosis), which is the most common type, and on ATTR amyloidosis, which is now being diagnosed much more frequently than in the past.
