EM (MC1R) Locus - Melanistic Mask
US$ 75.00 RRP

Category: Trait (Associated with Phenotype)

Gene: MC1R

Variant Detected: Base Substitution G>A

Severity: Scale 1 has a very low degree of severity. It is a trait and so is tested based on preference, not usually for health concerns.

Mode of Inheritance: Autosomal Recessive

Test Overview: The Em variant of the MC1R gene at the extension (E/e) Locus results in the localized distribution of eumelanin (black pigment) on the muzzle of the dog which resembles a dark "mask" on dogs with lighter colored coats. Although the Em variant produces a black melanistic mask, the final color of a dog's mask is dependent on other DNA variants such as the B and D loci that modify the production or appearance of the eumelanin (black pigment) in the dog. For example, dogs that are b/b at the B locus will have brown masks due to the disruption of eumelanin synthesis that results in the conversion of black pigmented areas to brown.
