The Champagne mutation is a dominant allele in the gene SLC36A1 (solute carrier family 36, member 1) located in the fourteenth chromosome. The mutant allele dilutes both eumelanin and pheomelanin. Eumelanin under the influence of the mutant allele results in chocolate or yellowish-brown color, and pheomelanin results in in light orange or golden yellow. This Champagne allele has the symbol “Ch,” and the “wild” recessive allele is designated “ch.” There is a DNA test for the Champagne gene. The influence of the Champagne gene on color is described in Table 6.
