富含亮氨酸重复激酶 2 (LRRK2) 突变是遗传相关帕金森病的最常见原因,通常与路易体病理相关;然而,tau、α-突触核蛋白和泛素病理学也有报道。我们报告了一名患者携带 LRRK2 G2019S 突变和微管相关蛋白 tau (MAPT) 外显子 4 中的新型杂合变异 c.370C>G、p.Q124E 的病例。该患者70多岁时出现帕金森症,左旋多巴反应良好。神经病理学分析显示黑质变性和阿尔茨海默型 tau 蛋白病理学无路易体。使用磷酸化 TDP-43 抗体进行免疫组织化学染色,发现海马体、颞叶新皮质、纹状体和黑质中偶尔存在 TDP-43 病理。然而,在皇后广场脑库中提供的路易体病理学的另外 4 个档案 LRRK2 G2019S 病例中,未发现 TDP-43 病理学。在其他已发表的携带 LRRK2 G2019S 突变的患者病例中,据报道只有 3 例接受了 TDP-43 病理学评估,结果呈阴性。 MAPT 变异在 LRRK2 病例临床和病理表现中的作用仍有待确定。
Leucine-rich repeat kinase 2 (LRRK2) mutation is the most common cause of genetic-related parkinsonism and is usually associated with Lewy body pathology; however, tau, α-synuclein, and ubiquitin pathologies have also been reported. We report the case of a patient carrying the LRRK2 G2019S mutation and a novel heterozygous variant c.370C>G, p.Q124E in exon 4 of the microtubule-associated protein tau (MAPT). The patient developed parkinsonism with good levodopa response in her 70s. Neuropathological analysis revealed nigral degeneration and Alzheimer-type tau pathology without Lewy bodies. Immunohistochemical staining using phospho-TDP-43 antibodies identified occasional TDP-43 pathology in the hippocampus, temporal neocortex, striatum, and substantia nigra. However, TDP-43 pathology was not identified in another 4 archival LRRK2 G2019S cases with Lewy body pathology available in the Queen Square Brain Bank. Among other published cases of patients carrying LRRK2 G2019S mutation, only 3 were reportedly evaluated for TDP-43 pathology, and the results were negative. The role of the MAPT variant in the clinical and pathological manifestation in LRRK2 cases remains to be determined.
