MiXcan: a framework for cell-type-aware transcriptome-wide association studies with an application to breast cancer

open access: yesNature Communications, 2023
Conventional transcriptome-wide association study (TWAS) approaches predict genetically regulated gene expression at the tissue level. Here, the authors develop a framework for cell-type-aware TWAS that predicts cell-type level expression from genotype ...

Novel Variance-Component TWAS method for studying complex human diseases with applications to Alzheimer's dementia.

open access: yesPLoS Genetics, 2021
Transcriptome-wide association studies (TWAS) have been widely used to integrate transcriptomic and genetic data to study complex human diseases. Within a test dataset lacking transcriptomic data, traditional two-stage TWAS methods first impute gene ...

Genome-wide and transcriptome-wide association studies of mammographic density phenotypes reveal novel loci

open access: yesBreast Cancer Research, 2022
Background Mammographic density (MD) phenotypes, including percent density (PMD), area of dense tissue (DA), and area of non-dense tissue (NDA), are associated with breast cancer risk. Twin studies suggest that MD phenotypes are highly heritable. However,

A transcriptome-wide association study of uterine fibroids to identify potential genetic markers and toxic chemicals

open access: yesPLoS ONE, 2022
Uterine fibroid is one of the most prevalent benign tumors in women, with high socioeconomic costs. Although genome-wide association studies (GWAS) have identified several loci associated with uterine fibroid risks, they could not successfully interpret ...

On the interpretation of transcriptome-wide association studies.

open access: yesPLoS Genetics, 2023
Transcriptome-wide association studies (TWAS) aim to detect relationships between gene expression and a phenotype, and are commonly used for secondary analysis of genome-wide association study (GWAS) results.

Transcriptome-wide association study of breast cancer risk by estrogen-receptor status [PDF]

open access: yes, 2020
Previous transcriptome-wide association studies (TWAS) have identified breast cancer risk genes by integrating data from expression quantitative loci and genome-wide association studies (GWAS), but analyses of breast cancer subtype-specific associations ...
