家族性淀粉样物多发性神经病变（英文：Familial amyloid polyneuropathy，简称FAP）是一种染色体显性遗传病，是致命且无法根治的神经病变，由葡萄牙神经学家Corino da Costa Andrade于1952年首先发现。患者肝脏缺乏一种分解淀粉样蛋白的酶，导致淀粉样蛋白不正常地累积，影响神经系统、心脏及其他器官的功能，通常在40岁前会因心脏衰竭而死亡。

Familial amyloid polyneuropathy (FAP), also called transthyretin-related hereditary amyloidosis, transthyretin amyloidosis abbreviated also as ATTR ( hereditary form), or Corino de Andrade's disease, is an autosomal dominant neurodegenerative disease. It is a form of amyloidosis, and was first identified and described by Portuguese neurologist Mário Corino da Costa Andrade, in 1952. FAP is distinct from senile systemic amyloidosis (SSA), which is not inherited, and which was determined to be the primary cause of death for 70% of supercentenarians who have been autopsied.
