The Mouse Genome Informatics Database is the authoritative source of official names for mouse genes, alleles, and strains. Nomenclature follows the rules and guidelines established by the International Committee on Standardized Genetic Nomenclature for Mice.

Rules and Guidelines

Genes, Alleles, and Mutations	Full Guide	Rules for Nomenclature of Genes, Genetic Markers, Alleles, and Mutations in Mouse and Rat
	Quick Guides	Quick Guide to Nomenclature for Genes Quick Guide to Nomenclature for Alleles and Mutations
	Checklist	Nomenclature Checklist (checklist for proposing a locus symbol)
Strains	Full Guide	Rules and Guidelines for Nomenclature of Mouse and Rat Strains
Aberrations	Full Guide	Rules for Nomenclature of Chromosome Aberrations
