Genetic relationship of affected and carrier dogs identified in Japan between 2000 and 2011. The analysis was carried out using pedigree papers issued by the Japan Kennel Club and the Kennel Club of Japan and information reported by the New South Wales Border Collie Club (NSWBCC) and the Border Collie Database. The gray area indicates a border between Oceania and Japan. Dogs imported from Oceania to Japan were marked with an asterisk (*). All dogs carrying the mutant allele shared a common ancestor (†) born in 1944 in Australia. Areas surrounded by a dashed line indicate the 4 kennels surveyed using a genotyping test.
