Genetic variants in the KRT71 gene can cause either a nearly hairless (Sphynx) or a curly coated...plus
Domestic cats have a variety of coat colors and hair types. Long and short hair phenotypes are common, but there are also other mutations that produce curly and nearly hairless coats. Two of these mutations are in the gene Keratin 71 (KRT71). The nearly hairless coat of the Sphynx breed (hr) is recessive to normal coat, and the curly coat of the Devon Rex (re) breed is recessive to the hairless Sphynx coat.
