Abstract
OBJECTIVE: To evaluate the breed distribution of the ABCB1-1Delta polymorphism in a large number of dogs in North America, including dogs of several herding breeds in which this polymorphism has been detected and other breeds in which this polymorphism has not yet been identified. DESIGN: Cross-sectional study. ANIMALS: 5,368 dogs from which buccal swab samples were collected for purposes of ABCB1 genotyping. PROCEDURES: From May 1, 2004, to September 30, 2007, DNA specimens derived from buccal swab samples collected from 5,368 dogs underwent ABCB1 genotyping. These data were reviewed, and results for each dog were recorded in a spreadsheet, along with the dog's breed. The genotypes for each breed were tallied by use of a sorting function. RESULTS: The ABCB1-1Delta allele was identified in 9 breeds of dogs and in many mixed-breed dogs. Breeds that had the ABCB1-1Delta allele included Collie, Longhaired Whippet, Australian Shepherd (standard and miniature), Shetland Sheepdog, Old English Sheepdog, Border Collie, Silken Windhound, and German Shepherd Dog (a breed in which this mutation had not been detected previously). CONCLUSIONS AND CLINICAL RELEVANCE: The ABCB1-1Delta polymorphism is associated with increased susceptibility to many adverse drug reactions and with suppression of the hypothalamic-pituitary-adrenal axis and is present in many herding breeds of dog. Veterinarians should be familiar with the breeds that have the ABCB1-1Delta polymorphism to make appropriate pharmacologic choices for these patients.
