Glossary Index

MGI Glossary

This glossary provides definitions for some terms found in our help documentation and other terms that are useful in understanding mouse genetics and bioinformatics. Terms are defined in a general sense as they apply to eukaryotic genetics, particularly mouse genetics; some terms are also defined as they are specifically used in MGI (e.g., gene). This list will grow as time goes on. If there is a term you think should be included in this list, please contact MGI User Support. There are a number of useful online glossaries in addition to this one:

The Mouse Developmental Anatomy Browser displays anatomical terms of the mouse in a hierarchical manner for a series of developmental stages, using standard anatomical nomenclature.
The Adult Mouse Anatomy Browser provides standardized nomenclature for anatomical structures in the postnatal mouse (Theiler stage 28).
The Gene Ontology definitions page provides current definitions of all terms used in the Gene Ontology Project.
The Glossary of Genetic Terms at the National Human Genome Research Institute defines basic genetic terms most relevant to human genetics. This glossary includes audio explanations and illustrations.
The Genome Glossary for the Human Genome Project defines many basic genetic terms.
The MeSH Browser at NCBI contains useful definitions of many terms, organized as a hierarchical controlled vocabulary.
The BLAST Glossary at NCBI defines terms used in searching sequence databases.
The Hypermedia Glossary of Genetic Terms by Birgid Schlindwein contains over 600 genetic terms.

If you find an online glossary that you think should be included here, please contact MGI User Support.
