Abstract
A hyperphosphorylated, ubiquitinated form of TDP-43, known as pathologic TDP-43, was shown to be a central component of ubiquitin-positive, tau-negative and alpha-synuclein-negative inclusions in frontotemporal lobar degeneration (FTLD-U)and amytrophic lateral sclerosis (ALS). To investigate the role of the TDP-43 gene in sporadic forms of frontotemporal dementia (FFD), we genotyped 10 single ...
Abstract
A hyperphosphorylated, ubiquitinated form of TDP-43, known as pathologic TDP-43, was shown to be a central component of ubiquitin-positive, tau-negative and alpha-synuclein-negative inclusions in frontotemporal lobar degeneration (FTLD-U)and amytrophic lateral sclerosis (ALS). To investigate the role of the TDP-43 gene in sporadic forms of frontotemporal dementia (FFD), we genotyped 10 single nucleotide polymorphisms covering the entire TDP-43 genomic region. including the MASP2 gene in 173 patients with sporadic FTD (including 7 patients that were diagnosed with FTD and ALS) and 184 matched controls from Germany. Although we could observe a weak trend towards a potential disease association in a few FTD/ALS patients, no significant association with sporadic FTD could be demonstrated. There is no evidence. that common variants in TDP-43 confer a strong risk to the development of sporadic FTD. (C) 2007 Elsevier Inc. All rights reserved.
