Phenotype: Dogs with the curl variant have curly coats or wavy coats depending on how many copies of the variant they possess.
Mode of Inheritance: Incomplete dominance
Alleles: N = No curl, C = Curl
Breeds appropriate for testing: Many breeds including Airedale Terrier, American Water Spaniel, Australian Labradoodle, Bichon Frise, Boykin Spaniel, Chesapeake Bay Retriever, Dachshund, Fox Terrier (Wire-haired), Goldendoodle, Havanese, Irish Water Spaniel, Kerry Blue Terrier, Kuvasz, Labradoodle, Maltese, Poodle, Portuguese Water Dog, Soft Coated Wheaten Terrier, Welsh Terrier, and Crossbreeds
Explanation of Results:
Dogs with N/N genotype are expected to have a straight coat. They cannot transmit this curl variant to their offspring.
Dogs with N/C genotype are expected to have a wavy coat. They may transmit this curl variant to 50% of their offspring. Matings between two N/C dogs are expected to produce 50% puppies with wavy hair and 25% puppies with curly hair.
Dogs with C/C genotype are expected to have a curly coat. They will transmit this curl variant to all of their offspring.

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.
