We report a novel transthyretin variant, Gly53Ala, in a 44-year-old British woman who presented with severe episodic headaches, often with focal neurological deficit, before developing progressive ataxia, depression, dementia and eventually peripheral neuropathy. Transthyretin amyloidosis was confirmed on biopsy of the heart muscle. Serum amyloid P component scintigraphy did not show visceral amyloid in extra-cardiac sites, but magnetic resonance imaging indicated diffuse leptomeningeal amyloidosis.
我们报告了一名44岁英国女性中的一种新型转甲状腺素蛋白变体,即甘氨酸53位突变为丙氨酸,该患者在出现进行性共济失调、抑郁、痴呆并最终发展为周围神经病变之前,表现为严重的发作性头痛,常伴有局灶性神经功能缺损。心肌活检证实为转甲状腺素蛋白淀粉样变性。血清淀粉样蛋白P成分闪烁扫描未显示心脏外部位的内脏淀粉样变性,但磁共振成像显示弥漫性软脑膜淀粉样变性。
