A member of a family with an autosomal dominant pattern of frontotemporal dementia (FTD) with a TDP-43 pathological substrate in other members and no mutations in FTD-associated genes developed behavioral variant FTD followed by Progressive Supranuclear Palsy. Autopsy revealed a pure tauopathy of PSP pattern.
The findings raise the possibility of shared pathogenic pathways and a proximal genetic abnormality between PSP and FTLD-43.
一个家族中,有成员患常染色体显性额颞叶痴呆(FTD),其他成员有TDP - 43病理底物且FTD相关基因无突变,该家族一名成员先出现行为变异型FTD,随后发展为进行性核上性麻痹。尸检显示为PSP型的纯tau蛋白病。
这些发现增加了PSP和FTLD - 43之间存在共同致病途径和近端基因异常的可能性。
