Description

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.
