ArrayExpress - functional genomics data
ArrayExpress is a database of functional genomics experiments that can be queried and the data downloaded. It includes gene expression data from microarray and high throughput sequencing studies. Data is collected to MIAME and MINSEQE standards. Experiments are submitted directly to ArrayExpress or are imported from the NCBI GEO database.

20 September 2013 - Linking genetic variation to differences in gene expression
What are the functional consequences of genetic variation? A study published this week in Nature has used RNA-seq data from over 450 individuals, whose genome sequences are already published as part of the 1000 Genomes Project, to investigate how genetic variation affects the regulation of gene expression. This information can give clues for the diagnosis and treatment of different diseases. The work was led by researchers from the Faculty of Medicine at the University of Geneva as part of the GEUVADIS project. The data from the study are available in ArrayExpress under accession E-GEUV-3. Find out more about the story in EBI's press release.
