Mashup Score: 1Full expression and splicing QTL summary statistics for three human spinal cord segments - 1 year(s) ago
This dataset is part of the manuscript: “Integrative genetic analysis of the amyotrophic lateral sclerosis spinal cord implicates glial activation and suggests new risk genes” by Jack Humphrey, et al. The files below contain nominal and permuted quantitative trait loci (QTL) associations between common genetic variants derived from whole genome sequencing and either gene expression or splicing…

Mashup Score: 0Meta-imputation of transcriptome from genotypes across multiple datasets by leveraging publicly available summary-level data - 2 year(s) ago
Author summary The gene expression levels within a cell are affected by various factors, including DNA variation, cell type, cellular microenvironment, disease status, and other environmental factors surrounding the individual. The genetic component of gene expression is known to explain a substantial fraction of transcriptional variation among individuals and can be imputed from genotypes in a…

Mashup Score: 5
Author summary Transcriptome-wide association studies (TWAS) are a type of bioinformatics methodology for identifying complex trait-associated genes. There have been various TWAS methods, each developed under distinct biological assumptions of how genes contribute to complex traits. It is unclear, however, how powerful different TWAS methods are under a variety of biological scenarios. Here, we…

Mashup Score: 3
Author summary Transcriptome-wide association studies (TWAS) can improve the statistical power of genetic association studies by leveraging the relationship between genetically predicted transcript expression levels and an outcome. We propose a new TWAS pipeline that integrates data on the genetic regulation of expression levels across multiple tissues. We generate cross-tissue expression…

Mashup Score: 6Novel Variance-Component TWAS method for studying complex human diseases with applications to Alzheimer’s dementia - 3 year(s) ago
Author summary Traditional Transcriptome-wide association studies (TWAS) tools make strong assumptions about the relationships among genetic variants, transcriptome, and phenotype that may be violated in practice, thereby substantially reducing the power. Here, we propose a Variance-Component TWAS method (VC-TWAS) that relaxes these assumptions and can be implemented with both individual-level…

Mashup Score: 0Power analysis of transcriptome-wide association study: Implications for practical protocol choice - 3 year(s) ago
Author summary We compared the effectiveness of three methods for finding genetic effects on disease in order to quantify their strengths and help researchers choose the best protocol for their data. The genome-wide association study (GWAS) is the standard method for identifying how the genetic differences between individuals relate to disease. Recently, the transcriptome-wide association study…
