A variant in the Keratin-71 (KRT71) gene is associated with curly hair in dogs. This variant is likely inherited as an incomplete dominant trait, which means that dogs with two copies of the variant (C/C) have curly coats and dogs with one copy of the variant (N/C) are not curly but have wavy coats.

This test assays the p.Arg151Trp variant in KRT71.
