The familial amyloid neuropathies (or familial amyloidotic neuropathies, neuropathic heredofamilial amyloidosis, familial amyloid polyneuropathy) are a rare group of autosomal dominant diseases wherein the autonomic nervous system and/or other nerves are compromised by protein aggregation and/or amyloid fibril formation. ==Classification== The aggregation of one precursor protein leads to peripheral neuropathy and/or autonomic nervous system dysfunction. These proteins include: transthyretin (ATTR, the most commonly implicated protein), apolipoprotein A1, and gelsolin. Due to the rareness of the other types of familial neuropathies, transthyretin amyloidogenesis-associated polyneuropathy should probably be considered first. "FAP-I" and "FAP-II" are associated with transthyretin.〔 (Senile systemic amyloidosis is also associated with transthyretin aggregation.) "FAP-III" is also known as "Iowa-type", and involves apolipoprotein A1. "FAP-IV" is also known as "Finnish-type", and involves gelsolin. Fibrinogen, apolipoprotein A1, and lysozyme are associated with a closely related condition, familial visceral amyloidosis. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Familial amyloid neuropathy」の詳細全文を読む スポンサード リンク
