  • Draft for a Discussion on Basic Genetics.Pdf
    2 Foreword. “Mens sana in corpore sano” : a healthy mind in a healthy body. The health of the Rottweiler, worldwide, lies close to our heart and is embedded in the Constitution of the International Federation of Rottweilerfriends (IFR). It’s reference to the health of all breeding dogs, implies that the Federation and its Memberclubs must pay particular attention to genetic disorders. For the Rottweiler, Hip Dysplasia (HD) and Elbow Dysplasia (ED) were the first disorders that worldwide led to regulations meant to diminish the genetic affection of the breed. The measures that were taken by breed clubs and/or kennelclubs, mostly by excluding the dogs that are affected by the disease from breeding, have proven to be quite effective, although not enough to completely eliminate the genetic factor and remove it from the genepool Still they have helped to limit the number of affected dogs and to avoid a lot of suffering. In this brochure you will find a brief review of just a few of the genetic diseases that are said to have entered the Rottweiler’s genepool. 1 The list is not new, nor the particular diseases on it. Even the way of approaching the problem is known for a long time and was amongst others confirmed in the International Breeding Strategies of the FCI that were approved in 2009. Indeed, not just for the Rottweiler but for many other breeds too, cynology has sounded a loud alarm concerning an ever more reduced genetic diversity among certain canine breeds, causing not only extreme phenotypes (2) but also physical and health problems.

Mickelson1 & C. Drögemüller 2 Published: xx xx xxxx Canine leukoencephalomyelopathy (LEMP) is a juvenile-onset neurodegenerative disorder of the CNS white matter currently described in Rottweiler and Leonberger dogs. Genome-wide association study (GWAS) allowed us to map LEMP in a Leonberger cohort to dog chromosome 18. Subsequent whole genome re-sequencing of a Leonberger case enabled the identifcation of a single private homozygous non-synonymous missense variant located in the highly conserved metallo-beta-lactamase domain of the N-acyl phosphatidylethanolamine phospholipase D (NAPEPLD) gene, encoding an enzyme of the endocannabinoid system. We then sequenced this gene in LEMP-afected Rottweilers and identifed a diferent frameshift variant, which is predicted to replace the C-terminal metallo-beta-lactamase domain of the wild type protein. Haplotype analysis of SNP array genotypes revealed that the frameshift variant was present in diverse haplotypes in Rottweilers, and also in Great Danes, indicating an old origin of this second NAPEPLD variant. The identifcation of diferent NAPEPLD variants in dog breeds afected by leukoencephalopathies with heterogeneous pathological features, implicates the NAPEPLD enzyme as important in myelin homeostasis, and suggests a novel candidate gene for myelination disorders in people.

The aim of this study was genomic charac- terization (107,403 autosomal SNPs) of the three LGD breeds from the Balkans (Karst Shepherd, Sharplanina Dog, and Tornjak). Our analyses were performed on 44 dogs representing three Balkan LGD breeds, as well as on 79 publicly available genotypes representing eight other LGD breeds, 70 individuals representing seven popular breeds, and 18 gray wolves. The results of multivariate, phylogenetic, clustering (STRUCTURE), and FST differentiation analyses showed that the three Balkan LGD breeds are genetically distinct populations. While the Sharplanina Dog and Tornjak are closely related to other LGD breeds, the Karst Shepherd is a slightly genetically distinct population with estimated influence from German Shepard (Treemix analysis). Estimated genomic diversity was high with low inbreeding in Sharplanina Dog (Ho = 0.315, He = 0.315, and FROH>2Mb = 0.020) and Citation: Janeš, M.; Zorc, M.; Tornjak (Ho = 0.301, He = 0.301, and FROH>2Mb = 0.033) breeds.

C. Phillips Received: 23 March 2017; Accepted: 27 May 2017; Published: 30 May 2017 Simple Summary: Birth weight is a key factor for neonatal mortality and morbidity in most mammalian species. The great morphological variability in size, body weight and breed, as well as in skeletal and cranial conformation makes it challenging to define birth weight standards in dogs. A total of 3293 purebred pups were surveyed to study which maternal aspects can determine birth weight considering head and body shape, size, body weight and breed in bitches, as well as litter size and sex in pups. In our sample, multivariate analysis outcomes suggested that birth weight and litter size were directly proportional to maternal size. The maternal body shape influenced both birth weight and litter size, whereas the maternal head shape had impact only on birth weight. Sex differences in birth weight were found. Birth weight and litter size also varied among breeds.

  • A GJA9 Frameshift Variant Is Associated with Polyneuropathy in Leonberger Dogs Doreen Becker1†, Katie M
    Becker et al. BMC Genomics (2017) 18:662 DOI 10.1186/s12864-017-4081-z RESEARCHARTICLE Open Access A GJA9 frameshift variant is associated with polyneuropathy in Leonberger dogs Doreen Becker1†, Katie M. Minor2†, Anna Letko1†, Kari J. Ekenstedt2,3, Vidhya Jagannathan1, Tosso Leeb1, G. Diane Shelton4, James R. Mickelson2† and Cord Drögemüller1*† Abstract Background: Many inherited polyneuropathies (PN) observed in dogs have clinical similarities to the genetically heterogeneous group of Charcot-Marie-Tooth (CMT) peripheral neuropathies in humans. The canine disorders collectively show a variable expression of progressive clinical signs and ages of onset, and different breed prevalences. Previously in the Leonberger breed, a variant highly associated with a juvenile-onset PN was identified in the canine orthologue of a CMT-associated gene. As this deletion in ARHGEF10 (termed LPN1) does not explain all cases, PN in this breed may encompass variants in several genes with similar clinical and histopathological features. Results: A genome-wide comparison of 173 k SNP genotypes of 176 cases, excluding dogs homozygous for the ARHGEF10 variant, and 138 controls, was carried out to detect further PN-associated variants. A single suggestive significant association signal on CFA15 was found. The genome of a PN-affected Leonberger homozygous for the associated haplotype was sequenced and variants in the 7.7 Mb sized critical interval were identified. These variants were filtered against a database of variants observed in 202 genomes of various dog breeds and 3 wolves, and 6 private variants in protein-coding genes, all in complete linkage disequilibrium, plus 92 non-coding variants were revealed.
