The colour variant Gold or Sunshine is a modification of the tabby coat, which is described for Siberian, Kurilian Bobtail and Toy Bob. A mutation in the CORIN gene causes an enlargement of the pheomelanin band of the hair. Affected animals are characterized by an enlightenment of the tabby markings, a cream to white area around the nose extending to the chest, and a pink nose without the dark outline typical of tabby cats. The colour variation can only occur if the cat has the genotype A/A or A/a at the agouti locus. A second mutation leads to an even stronger colour modification called extreme sunshine". Extreme-sunshine cats show a strong enlightenment of the tabby marks, light-cream belly and the same pink nose lacking the dark line observed in sunshine cats. The allelic series for this inheritance is N > wbeSib > wbSib."
