Description:
Cocoa is the brown coat colour phenotype associated and see in some 'bull' breeds most commonly the French Bulldog. Cocoa (Co) is inherited in an autosomal recessive manner. The variant for cocoa is found in seperate gene to the other Brown (B) variants.
Test Overview:
A variant in the murine Hps3 gene has been found to cause brown coat color in the cocoa mouse mutant. This was genotyped in a population of 373 French Bulldogs and found a strong association of the homozygous mutant HPS3 genotype with the brown coat color. This brown is referred to as 'cocoa' in the french bulldog and tends to be slightly 'darker' than the regular brown/chocolate phenotype seen in other breeds.
