Category: Trait (Associated with Phenotype)

Gene: PSMB7

Variant Detected: Base Substitution T>C

Severity: Scale 3 has a moderate degree of severity, as it is not a fatal disease, though it can decrease the quality of life.

Mode of Inheritance: Autosomal Dominant

Test Overview: The Harlequin gene causes a white background and the spots increase in size. Dogs that are not merle, cannot express the Harlequin colour/pattern. Breeding two dogs that both have a copy of the h locus “NH” is not recommended. A dog with two copies of Harlequin has not been observed and It is presumed to be lethal in utero. This gene is inherited as a dominant trait.
