  • As part of the enhanced GTEx (eGTEx) project, 987 human samples from 9 tissue types and 424 donors are assayed using DNA methylation microarrays. Colocalization of GWAS variants, eQTLs and mQTLs shows diverse links between genetic variation, molecular phenotypes and complex traits.

  • Most expression QTLs (eQTLs) co-occur with a DNA methylation QTL (meQTL), suggesting a common causal variant. Here the authors analyse DNA and RNA from blood and identify eQTL-meQTL pairs likely to share a causal variant, finding that expression and methylation are often genetically co-regulated.

  • Using the GTEx data and others, a comprehensive analysis of adenosine-to-inosine RNA editing in mammals is presented; targets of the various ADAR enzymes are identified, as are several potential regulators of editing, such as AIMP2.

  • Multiple transcriptome approaches, including single-cell sequencing, demonstrate that escape from X chromosome inactivation is widespread and occasionally variable between cells, chromosomes, and tissues, resulting in sex-biased expression of at least 60 genes and potentially contributing to sex-specific differences in health and disease.

  • The authors show that rare genetic variants contribute to large gene expression changes across diverse human tissues and provide an integrative method for interpretation of rare variants in individual genomes.

  • Phenotypic variation and diseases are influenced by factors such as genetic variants and gene expression. Here, Barbeira et al. develop S-PrediXcan to compute PrediXcan results using summary data, and investigate the effects of gene expression variation on human phenotypes in 44 GTEx tissues and >100 phenotypes.

  • Genetic variants have been associated with myriad molecular phenotypes that provide new insight into the range of mechanisms underlying genetic traits and diseases. Identifying any particular genetic variant's cascade of effects, from molecule to individual, requires assaying multiple layers of molecular complexity. We introduce the Enhancing GTEx (eGTEx) project that extends the GTEx project to combine gene expression with additional intermediate molecular measurements on the same tissues to provide a resource for studying how genetic differences cascade through molecular phenotypes to impact human health.
