Altered plasma protein profiles in genetic FTD – a GENFI study
Ullgren, Abbe; Öijerstedt, Linn; Olofsson, Jennie; Bergström, Sofia; Remnestål, Julia; van Swieten, John C.; Jiskoot, Lize C.; Seelaar, HarroBackground: Plasma biomarkers reflecting the pathology of frontotemporal dementia would add significant value to clinical practice, to the design and implementation of treatment trials as well as our understanding of disease mechanisms. The aim of this study was to explore the levels of multiple plasma proteins in individuals from families with genetic frontotemporal dementia. Methods: Blood samples from 693 pa...
Age at symptom onset and death and disease duration in genetic frontotemporal d...
Moore, Katrina M.; Nicholas, Jennifer; Grossman, Murray; McMillan, Corey T.; Irwin, David J.; Massimo, Lauren; Van Deerlin, Vivianna M.Background: Frontotemporal dementia is a heterogenous neurodegenerative disorder, with about a third of cases being genetic. Most of this genetic component is accounted for by mutations in GRN, MAPT, and C9orf72. In this study, we aimed to complement previous phenotypic studies by doing an international study of age at symptom onset, age at death, and disease duration in individuals with mutations in GRN, MAPT,...
TBK1 mutation spectrum in an extended European patient cohort with frontotempor...
van der Zee, Julie; Gijselinck, Ilse; Van Mossevelde, Sara; Perrone, Federica; Dillen, Lubina; Heeman, Bavo; Bäumer, Veerle; Engelborghs, SebastiaanWe investigated the mutation spectrum of the TANK-Binding Kinase 1 (TBK1) gene and its associated phenotypic spectrum by exonic resequencing of TBK1 in a cohort of 2,538 patients with frontotemporal dementia (FTD), amyotrophic lateral sclerosis (ALS), or FTD plus ALS, ascertained within the European Early-Onset Dementia Consortium. We assessed pathogenicity of predicted protein-truncating mutations by measuring...
A comprehensive study of the genetic impact of rare variants in SORL1 in Europe...
Verheijen, Jan; Van den Bossche, Tobi; van der Zee, Julie; Engelborghs, Sebastiaan; Sanchez-Valle, Raquel; Lladó, Albert; Graff, CarolineThe sortilin-related receptor 1 (SORL1) gene has been associated with increased risk for Alzheimer's disease (AD). Rare genetic variants in the SORL1 gene have also been implicated in autosomal dominant early-onset AD (EOAD). Here we report a large-scale investigation of the contribution of genetic variability in SORL1 to EOAD in a European EOAD cohort. We performed massive parallel amplicon-based re-sequencing...
Rare variants in PLD3 do not affect risk for early-onset Alzheimer disease in a...
Cacace, Rita; Van den Bossche, Tobi; Engelborghs, Sebastiaan; Geerts, Nathalie; Laureys, Annelies; Dillen, Lubina; Graff, Caroline; Thonberg, HåkanRare variants in the phospholipase D3 gene (PLD3) were associated with increased risk for late-onset Alzheimer disease (LOAD). We identified a missense mutation in PLD3 in whole-genome sequence data of a patient with autopsy confirmed Alzheimer disease (AD) and onset age of 50 years. Subsequently, we sequenced PLD3 in a Belgian early-onset Alzheimer disease (EOAD) patient (N = 261) and control (N = 319) cohort,...
