There are many types of hereditary amyloidosis associated with different gene mutations and abnormal proteins. The most common type of hereditary amyloidosis is transthyretin amyloidosis (ATTR),a condition in which the amyloid deposits are most often made up of the transthyretin protein which is made in the liver. Other examplesof hereditary amyloidosis include, but are not limited to, apolipoprotein AI amyloidosis (A ApoAI), gelsolin amyloidosis (A Gel), lysozyme amyloidosis (A Lys), cystatin C amyloidosis (A Cys), fibrinogen Aα-chain amyloidosis (A Fib), and apolipoprotein AII amyloidosis (A ApoAII). Most types of hereditary amyloidosis are inherited in an autosomal dominant manner. Treatment is focused on addressing symptoms of organ damage and slowing down the production of amyloid when possible through methods such as liver transplants.
