Species-specific description: See also: OMIA:001199-9615 : Coat colour, extension in Canis lupus familiaris
Molecular basis: By cloning and sequencing a very likely candidate gene (based on knowledge that the mask phenotype is due to an allele at the Extension locus, which is known to be encoded by the MC1R gene), Schmutz et al. (2003) reported that "All dogs with a melanistic mask had at least one copy of a valine substitution for methionine at amino acid 264 (M264V)", resulting from "an A to G transition in the first position of codon 264" in the canine MC1R gene.

Variants
By default, variants are sorted chronologically by year of publication, to provide a historical perspective.
Readers can re-sort on any column by clicking on the column header. Click it again to sort in a descending
order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column
headers.
WARNING! Inclusion of a variant in this table does not automatically mean that it should be used for DNA testing. Anyone contemplating the use of any of these variants for DNA testing should examine critically the relevant evidence (especially in breeds other than the breed in which the variant was first described). If it is decided to proceed, the location and orientation of the variant sequence should be checked very carefully.
Since October 2021, OMIA includes a semiautomated lift-over pipeline to facilitate updates of genomic positions to a recent reference genome position. These changes to genomic positions are not always reflected in the ‘acknowledgements’ or ‘verbal description’ fields in this table.
