ABSTRACT
A deletion mutation in the canine multidrug resistance (MDR1) gene provokes drug sensitivity in several dog breeds from the Collie lineage. A haplotype of four microsatellites containing this mdr1-1Delta mutation was conserved among affected breeds. In this study, we analysed the haplotypes of the MDR1 flanking region of 177 dogs of the breed Elo which is composed of several dog breeds including the Old English sheepdog from the Collie lineage. We detected a haplotype in the Elo breed which had previously been associated with the mutant mdr1-1Delta allele in Old English sheepdogs. Using a regression analysis for the probability of the haplotype on the proportion of genes of the founder breeds, we could exclude the Old English sheepdog as origin of this haplotype for the Elo breed. The MDR1 flanking region could be traced back to the Japanese Spitz as one of the founder dog breeds of the Elo and thus, the introgression of the mdr1-1Delta mutation into the dog breed Elo through the Collie lineage is very unlikely.
