A broader view of the diversity of human gene expression

Differences in gene expression between individuals are an important source of variation in traits and diseases. However, most of the research into such differences in humans has focused on individuals of European ancestries, limiting its generalizability. A geographically diverse, open-access gene-expression resource now enables the exploration of variation of gene expression in under-represented populations. An RNA-sequencing data set compiled from individuals from around the world provides insights into variation in gene expression.
