The familial amyloid neuropathies (or familial amyloidotic neuropathies, neuropathic heredofamilial amyloidosis, familial amyloid polyneuropathy) are a rare group of autosomal dominant neuropathies of autonomic and peripheral nerves.
Classification
The precursor proteins are: transthyretin (ATTR, the most commonly implicated protein), apolipoprotein A1, and gelsolin.
Due to the rareness of the other types, it is sometimes associated with transthyretin alone.[1]
"FAP-I" and "FAP-II" are associated with transthyretin.[2] (Senile systemic amyloidosis is also associated with transthyretin.)
"FAP-III" is also known as "Iowa-type", and involves apolipoprotein A1.[2]
"FAP-IV" is also known as "Finnish-type", and involves gelsolin.[3]
Fibrinogen, apolipoprotein A1, and lysozyme are associated with a closely related condition, familial visceral amyloidosis.
Treatment
Liver transplantation has demonstrated moderate improvement in ATTR familial amyloidosis.[4]
