OMIA 001416-9614 : Coat colour, dominant black in Canis latrans

In other species: dog , gray wolf , water buffalo

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal

Considered a defect: no

Key variant known: yes

Year key variant first reported: 2009

Cross-species summary: Also known as the K locus

Molecular basis: Anderson et a. (2009) showed that the 3bp deletion of the CBD103 gene that causes dominant black in dogs, exists also in the orthologous gene in wolves and coyotes, and is strongly associated with black coat colour in both these species.

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.
