The MGI Expression1 Detected (Not Detected) ontology contains genes expressed (not expressed) in specific anatomical structures at specific developmental stages (Theiler stages) in mouse. The information is primarily obtained by curators from the literature. The anatomy for each developmental stage is represented by a directed acyclic graph that gives a hierarchy of anatomical terms and their relationships.
The human MGI Expression ontologies are derived by mapping expression information from all genes in the mouse ontologies to their human orthologs. In general, it is unclear if the expression pattern of the orthologous human gene has diverged.
The human hg19 ontology contains 6,983 expression entries, 8,143 genes, and 486,114 total term <--> gene associations.
The human hg18 ontology contains 6,999 expression entries, 8,132 genes, and 486,104 total term <--> gene associations.
The mouse mm9 ontology contains 6,989 expression entries, 8,467 genes, and 495,761 total term <--> gene associations.
All data for this ontology was downloaded on August 20, 2010.
