Apolipoprotein A-1 (ApoA-1) amyloidosis occurs as a nonhereditary condition in atherosclerotic plaques, but it can also manifest as a hereditary disorder caused by mutations of the APOA1 gene. Hereditary ApoA-1 amyloidosis presents with diverse organ involvement based on the position of the mutation. We describe a case of ApoA-1 amyloidosis with a Glu34Lys mutation; testicular, conjunctival, and renal involvement; and the notable finding of lipid deposition within the amyloid deposits.
载脂蛋白A-1(ApoA-1)淀粉样变性在动脉粥样硬化斑块中以非遗传性疾病形式出现,但也可表现为由APOA1基因突变引起的遗传性疾病。遗传性ApoA-1淀粉样变性根据突变位置表现出不同器官受累情况。我们描述了一例具有Glu34Lys突变、睾丸、结膜和肾脏受累以及淀粉样沉积物内脂质沉积这一显著发现的ApoA-1淀粉样变性病例。
