Abstract

Though distinct pathological entities, corticobasal degeneration (CBD) and progressive supranuclear palsy (PSP) share multiple biochemical and genetic features suggesting overlapping pathophysiology. We report the case of a patient with an 18-year clinical course consistent with behavioral variant frontotemporal dementia. The neuropathological assessment revealed unclassifiable frontotemporal lobar degeneration with tau-immunoreactive inclusions sharing features of both CBD and PSP. Whole-genome sequencing revealed a unique combination of pleiotropic genetic risk variants associated with both PSP and CBD. These findings support the observation that CBD and PSP share genetic co-expression networks that influence neurodegenerative pathogenesis common to 4R tauopathies.

摘要

虽然皮质基底节变性 (CBD) 和进行性核上性麻痹 (PSP) 是两种不同的病理实体,但它们具有多种生化和遗传特征,表明它们具有重叠的病理生理学机制。我们报告了一例临床病程为 18 年的患者,其临床表现符合行为变异型额颞叶痴呆。神经病理学评估显示,非典型额颞叶 lobar 变性,伴有 tau 免疫反应性包涵体,具有 CBD 和 PSP 的共同特征。全基因组测序显示,与 PSP 和 CBD 相关的多种遗传风险变异的独特组合。这些发现支持了这样一种观察结果,即 CBD 和 PSP 共享遗传共表达网络,这些网络影响与 4R tau 病共有的神经退行性发病机制。
