Many canine immune-mediated diseases have strong breed predispositions and are believed to be inherited. However, the genetic mutations that cause these diseases are mostly unknown. As many immune-mediated diseases in humans share polymorphisms among a common set of genes, we conducted a candidate gene study of 15 of these genes across four immune-mediated diseases (immune-mediated hemolytic anemia, immune-mediated thrombocytopenia, immune-mediated polyarthritis (IMPA), and atopic dermatitis) in 195 affected and 206 unaffected dogs to assess whether causative or predictive polymorphisms might exist in similar genes in dogs. We demonstrate a strong association (Fisher’s exact p = 0.0004 for allelic association, p = 0.0035 for genotypic association) between two polymorphic positions (10 bp apart) in exon 2 of one allele in DLA-79, DLA-79*001:02, and multiple immune-mediated diseases. The frequency of this allele was significantly higher in dogs with immune-mediated disease than in control dogs (0.21 vs. 0.12) and ranged from 0.28 in dogs with IMPA to 0.15 in dogs with atopic dermatitis. This allele has two non-synonymous substitutions (compared with the reference allele, DLA-79*001:01), resulting in F33L and N37D amino acid changes. These mutations occur in the peptide-binding pocket of the protein, and based upon our computational modeling studies, are likely to affect critical interactions with the peptide N-terminus. Further studies are warranted to confirm these findings more broadly and to determine the specific mechanism by which the identified variants alter canine immune system function.}, number={3}, journal={Immunogenetics}, publisher={Springer Science and Business Media LLC}, author={Friedenberg, Steven G. and Buhrman, Greg and Chdid, Lhoucine and Olby, Natasha J. and Olivry, Thierry and Guillaumin, Julien and O’Toole, Theresa and Goggs, Robert and Kennedy, Lorna J. and Rose, Robert B. and et al.}, year={2015}, month={Dec}, pages={205–217} } @article{meurs_stern_reina-doreste_maran_chdid_lahmers_keene_mealey_2015, title={Impact of the canine double-deletion beta 1 adrenoreceptor polymorphisms on protein structure and heart rate response to atenolol, a beta 1-selective beta-blocker}, volume={25}, ISSN={["1744-6880"]}, DOI={10.1097/fpc.0000000000000152}, abstractNote={Objective &bgr;-Adrenergic receptor antagonists are widely utilized for the management of cardiac diseases in dogs. We have recently identified two deletion polymorphisms in the canine adrenoreceptor 1 (ADRB1) gene. We hypothesized that canine ADRB1 deletions would alter the structure of the protein, as well as the heart rate response to the &bgr;-adrenergic receptor antagonist, atenolol. The objectives of this study were to predict the impact of these deletions on the predicted structure of the protein and on the heart rate response to atenolol in a population of healthy adult dogs. Methods Eighteen apparently healthy, mature dogs with (11) and without (seven) ADRB1 deletions were evaluated. The heart rate of the dogs was evaluated with a baseline ambulatory ECG before and 14–21 days after atenolol therapy (1 mg/kg orally q12 h). Minimum, average, and maximum heart rates were compared between groups of dogs (deletions, controls) using an unpaired t-test and within each group of dogs using a paired t-test. The protein structure of ADRB1 was predicted by computer modeling. Results Deletions were predicted to alter the structure of the ADRB1 protein. The heart rates of the dogs with deletions were lower than those of the control dogs (the average heart rates were significantly lower). Conclusion ADRB1 deletions appear to have structural and functional consequences. Individual genome-based treatment recommendations could impact the management of dogs with heart disease.}, number={9}, journal={PHARMACOGENETICS AND GENOMICS}, author={Meurs, Kathryn M. and Stern, Josh A. and Reina-Doreste, Yamir and Maran, Brian A. and Chdid, Lhoucine and Lahmers, Sunshine and Keene, Bruce W. and Mealey, Katrina L.}, year={2015}, month={Sep}, pages={427–431} } @article{meurs_chdid_reina-doreste_stern_2015, title={Polymorphisms in the canine and feline renin-angiotensin-aldosterone system genes}, volume={46}, ISSN={["1365-2052"]}, DOI={10.1111/age.12260}, abstractNote={Please note: The publisher is not responsible for the content or functionality of any supporting information supplied by the authors.
