The following table contains information on coat color genes described in mice and their human and zebrafish homologues. We have included both genes that have been cloned and those that have only been mapped. Some loci, such as Bcl2 and Brca1, are not obvious candidates for coat color loci, but mutations in these genes (sometimes as seen in a knockout) do result in a dilution of coat color, and thus have been included in this table. Currently there are 210 loci described in this table. We are actively updating this table with additional loci involved in pigmentation, therefore the number of loci shown will be increasing in the near future. We suggest you to visit this WEB page regularly to obtain the most updated information.
There are two sets of loci:

We hope that this table is of use to you. If you have any corrections or additions, please let us know at micemut@espcr.org. Though we have tried to make this information as accurate as possible, the ESPCR makes no guarantee as to the accuracy of this information.
Many of these coat color mutations can be obtained from the The Jackson Laboratory or the Mutant Mouse Regional Resource Centers or located in one of the several existing mouse repositories world wide, searchable through the International Mouse Strain Resource.
Appearance and coat colour descriptions from some of these mouse coat colour mutants are also available (with some pictures) at the Mouse Phenome Database.
The human gene mutation database is available at the HGMD of the University of Cardiff (registration required). The Albinism Database, at the University of Minnesota, includes mutations associated with all major known forms of oculocutaneous and ocular albinism. The Locus Specific Mutation Databases, at the Human Genome Variation Society, contain useful links to a variety of databases holding information about mutations of different genes.
Additional information can be found in the classical book "The Coat Colors of Mice" by Willys K. Silvers (Springer Verlag, 1979), available on-line, along with other related books, through the Mouse Genome Informatics WEB site of The Jackson Laboratory.
Note: The links under the "Current symbol" row contain the most current information from The Jackson Laboratory - Mouse Genome Informatics MGI
. The links under "Mouse Chromosome" and "Human Chromosome" contain all available molecular information at the ENSEMBL WEB
of the corresponding mouse and human genes, respectively. They also contain Mouse SNPs information
of the corresponding mouse gene and all associated SNPs of the corresponding human gene, from the Single Nucleotide Polymorphism (SNPs) database of NCBI
. The links under "Human Locus" or "Associated Disease" contain most updated information from the OMIM (Online Mendelian Inheritance of Man)
. Also, under "Associated Diseases" it is included a direct link to the Albinism Database
, held at the University of Minnesota, with information about mutations and polymorphisms of genes associated with different types of albinism. The column describing the corresponding protein encoded, includes a link, if available, to Gene Paint project
illustrating the results of in situ hybridisation experiments of this locus on mouse embryos. A link to all NCBI databases
(i.e. PubMed) with information about the gene or locus is also included. The links under "Murine Locus" provide illustrative images
, if available, of mice displaying the phenotype of some alleles of the corresponding gene. Currently, this WEB holds 84 mouse pictures. The zebrafish homologous loci, if available, have been included according to the Zebrafish Model Organism Database
. A whole list of zebrafish pigmentation mutants, irrespective whether they have its correlate in mammals or not, can be obtained by inspecting this list.
