Frontotemporal dementia (FTD) is the second most common cause of early-onset dementia after Alzheimer disease (AD). Efforts in the field mainly focus on familial forms of disease (fFTDs), while studies of the genetic etiology of sporadic FTD (sFTD) have been less common. In the current work, we analyzed 4,685 sFTD cases and 15,308 controls looking for common genetic determinants for sFTD. We found a cluster of variants at the (rs199443; = 2.5 × 10, OR = 1.27) and (rs6857; = 1.31 × 10, OR = 1.27) loci and a candidate locus on chromosome 3 (rs1009966; = 2.41 × 10, OR = 1.16) in the intergenic region between and , contributing to increased risk for sFTD through effects on expression and/or splicing in brain cortex of functionally relevant in- genes at the and - loci. The association with the (H1c clade) and - loci may suggest common genetic pleiotropy across FTD and progressive supranuclear palsy (PSP) ( and - loci) and across FTD, AD, Parkinson disease (PD), and cortico-basal degeneration (CBD) ( locus). Our data also suggest population specificity of the risk signals, with and loci associations mainly driven by Central/Nordic and Mediterranean Europeans, respectively. This study lays the foundations for future work aimed at further characterizing population-specific features of potential FTD-discriminant haplotype(s) and the functional involvement and contribution of the haplotype and - loci to pathogenesis of sporadic forms of FTD in brain cortex.

全基因组分析揭示了 MAPT、MOBP 和 APOE 位点在散发性额颞叶痴呆中的潜在作用



额颞叶痴呆(FTD)是继阿尔茨海默病(AD)之后早发性痴呆的第二常见原因。该领域的工作主要集中在家族形式疾病(fFTD)上,而对散发性 FTD(sFTD)的遗传病因学的研究则不太常见。在当前的工作中,我们分析了 4,685 例 sFTD 病例和 15,308 例对照,寻找 sFTD 的常见遗传决定因素。我们在 (rs199443; = 2.5 × 10, OR = 1.27) 和 (rs6857; = 1.31 × 10, OR = 1.27) 位点处发现了一组变异,并且在 3 号染色体上发现了一个候选位点 (rs1009966; = 2.41 × 10, OR = 1.16) 在 和 之间的基因间区域,通过影响 和 - 基因座上功能相关的 in- 基因在大脑皮层中的表达和/或剪接,导致 sFTD 风险增加。与 (H1c 分支) 和 - 基因座的关联可能表明 FTD 和进行性核上性麻痹 (PSP)(和 - 基因座)以及 FTD、AD、帕金森病 (PD) 和皮质基底节变性 (CBD) 之间存在共同的遗传多效性(轨迹)。我们的数据还表明风险信号的人群特异性,以及基因座关联分别主要由中欧/北欧和地中海欧洲人驱动。这项研究为未来的工作奠定了基础,旨在进一步表征潜在 FTD 判别单倍型的人群特异性特征,以及单倍型和基因座对大脑皮层散发形式 FTD 发病机制的功能参与和贡献。
