Coat Colour Gold (Extreme Sunshine)

Gold is a modification of the tabby coat. In the Siberian breed, a specific golden phenotype, named extreme-sunshine, has been described. The phenotype is caused by an autosomal recessive inheritance pattern within the CORIN (Corin, Serine Peptidase) gene. Variants in the this gene cause golden coat modifications in cats characterized by enlarged yellow bands in hairs and reduced dark tips (wideband phenotype). A second allelic variant is known to exist that leads to a sunshine phenotype.
