The Gene Expression Database (GXD) is a community resource of gene expressi
on information for the laboratory mouse. By combining the different types o
f expression data, GXD aims to provide increasingly complete information ab
out the expression profiles of genes in different mouse strains and mutants
, thus enabling valuable insights into the molecular networks that underlie
normal development and disease. GXD is integrated with the Mouse Genome Da
tabase (MGD). Extensive interconnections with sequence databases and with d
atabases from other species, and the development and use of shared controll
ed vocabularies extend GXD's utility for the analysis of gene expression in
formation. GXD is accessible through the Mouse Genome Informatics web site
at http://www.informatics.jax.org/ or directly at http://www.informatics.ja
