E Locus (Extension)

For an overview of dog coat color hierarchy continue to the article Introduction into coat color in dogs.

The MC1R-gen (Melanocortin 1 receptor) has been identified on the canine chromosome 5 (Schmutz et al. 2001). In this locus, 3 alleles E, e and EM are known. The original, so-called wild type allele E (non-mutated allele), the allele e created by mutation c.916C>T (Newton et al. 2000, Schmutz et al. 2002), which causes the loss of gene function and is responsible for bright red or yellow coat colour in genotype e/e.

Example of coat colour of a dog of genotype e/e:

Locus E - genotype e/e


The E-locus test is suitable in particular for the following breeds: Afghan, Australian cattle dog, Australian Shepherd, Beagle, Border collie, Brittany Spaniel, Cardigan Welsh Corgi, Chinese Shar-Pei, Chow Chow, Cocker Spaniel, Dachshund, Dalmatian, Doberman Pinscher, English Cocker Spaniel, English Setter, English Springer Spaniel, Field Spaniel, Flatcoated Retriever, Foxhound, French Bull Dog, German Longhaired Pointer, German Shepherd, German Wirehaired Pointer, Labrador Retriever, Lowchen, Pointer, Pomeranian, Poodle, Pudelpointer.
