Coat colour, melanistic mask(Em)
Also known as: Melanistic Mask · Em locus · Melanistic Masking · Dunkle Gesichtsmaske · E-Locus Mask · …
Overview
What it is
This is a benign genetic trait rather than a medical condition, affecting the pigmentation of the dog's coat and skin. It is caused by a specific variant on the E-locus (the MC1R gene) which controls the distribution of dark pigment. This autosomal-dominant trait simply causes a localized concentration of dark melanin on the face.
How it presents
Owners will notice a distinct dark or black coloration on the dog's muzzle and face from birth, which contrasts with the rest of the body. This visual feature is purely cosmetic and does not affect the dog's health or physical well-being.
Treatment
No treatment is necessary as this is a natural coat color variation. There are no associated veterinary health risks or costs, resulting in a lifelong cost of 0 EUR.
How it's tested
E-Lokus (Em-Allel) DNA-Test(E-Lokus (Em))
Primary testDNA testEin molekularbiologischer DNA-Test untersucht das MC1R-Gen auf das Vorhandensein des Em-Allels, welches die Ausprägung einer dunklen Gesichtsmaske steuert.
