Project Summary

We have previously identified a gene associated with Anal Furunculosis (AF) in a region of the genome that is rich in immune genes. We have now performed a whole genome scan comparing 24 German Shepherd dogs having AF with 36 unaffected control dogs, which has revealed 46 SNPs that are significantly associated with AF, and are spread over 18 different canine chromosomes. Four of these SNP associations are highly significant and give us great hope that we will be able to identify other genes/loci associated with this disease. If we can identify such genes, it may be possible to start selective breeding to reduce the risk of German Shepherd dogs developing AF.
