Available in PDF, EPUB and Kindle. Book excerpt: The domestic dog has advantageous genome information ideal for mapping genes that cause disease. Humans share many diseases with dogs, which makes dogs an ideal model for studying the comparative genetics of disease. The availability of a canine genome reference sequence and high density SNP chips has facilitated the study of inherited diseases in dogs. The identification of gene-causing diseases in dogs is of relevance for human health. Here we describe the identification of causative mutations for three different canine diseases in orthologs of genes associated with orthologous human diseases. Among these, we describe what may prove to be the first inherited canine disease to be identified by whole genome sequencing. We discuss the importance of these finding and suggest future studies for each project.

Book excerpt: The morphologic variability seen in the domestic dog, Canis lupus familiaris, is unique among mammals. Selective pressures imposed by humans have divided dogs into almost 400 separate breeds. Selection has also led to the development of approximately 450 hereditary diseases, many of which are limited to specific breeds. Over half of these diseases present with similar clinical characteristics to those of many human hereditary diseases, making the dog an ideal model for study of the genetic bases of such diseases. Many diseases do not have candidate genes or have too many candidates to characterize. This is exacerbated in complex diseases that are caused by several genes. Whole-genome scans can provide insight into diseases by identifying marker(s) that co-segregate with a disease phenotype. The Minimal Screening Set - 2 (MSS-2) is the most recent set of microsatellites suitable for whole-genome screens. The first objective of this work was to streamline genomic screens in order to efficiently analyze large numbers of animals. To this end, chromosome-specific microsatellite panels were developed for the MSS-2. Canine hip dysplasia (CHD) is the most common orthopedic disease of the dog. CHD primarily affects medium and large breed dogs, but is found in almost every breed. The major objective of this work was to use linkage analysis to identify chromosomal regions that contain genes that are involved in CHD. Two populations were screened using the MSS-2. The first was a small family of Boykin Spaniels, though no markers were statistically significant in a whole-genome screen. An outcrossed pedigree of Greyhound/Labrador Retrievers was created for quantitative trait loci (QTL) mapping of CHD. The informativeness of markers in the F2 and backcrossed generations were calculated to show the utility of using such a population. Other factors that affect the power of this pedigree to identify QTL were also highlighted. Chromosomes that were identified in a previous screen as harboring putative QTLs were examined using the chromosome-specific panels to further define and confirm the regions of interest. Although no markers reached statistical significance, several areas of interest were identified.

This book was released on 2013 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: The inherited diseases of the domestic dog mimic a wide spectrum of common human disorders. By identifying the genes that harbor the mutations underlying dog diseases we not only provide powerful diagnostic DNA tests for dog breeders their veterinarians and but also provide spontaneously occurring canine models for human diseases. Since the first high quality dog genome reference sequence was published and made publically accessible, various molecular strategies have been applied in the canine genetic studies including candidate gene analysis, linkage analysis, and genome-wide allele association studies. Most recently our lab has focused on the discovery of causal sequence variants in the next generation whole-genome sequences of individual affected dogs. This has enabled us to identify disease-causing genes in dogs with relevance for human health. We describe here the identification of causative mutations for three different canine diseases: neonatal cerebellar ataxia, canine degenerative myelopathy and canine multiple system degeneration. In addition, we discuss the potential importance of these canine diseases if used as human disease models.

Available in PDF, EPUB and Kindle. Book excerpt: Dogs of different breeds can range remarkably in size, shape, and behavior, and yet they all carry essentially the same genome, making them a particularly fascinating model for genome plasticity. The recent release of the complete sequence of the dog genome provides an exciting new context in which to consider such variation. Twentyfive chapters written by experts in the field include various aspects of morphological and behavioral variation in dogs, their origins and domestication, and their unique value as a model system for many common but complex human diseases such as diabetes and cancer.

Gilliam (Jr.) and published by . This book was released on 2016 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: The genome of Canis lupus familiaris, the domestic dog, is an ideal tool for the study of inherited diseases. Its genome is uniquely suited for the mapping of genes that cause disease, and its reference genome has been published since 2008. Dogs and humans share many of the same diseases, making them an ideal model for the study of comparative genetics. The identification of disease-causing genes in dogs has relevance to human health. We here describe the identification of causal mutations for three different canine diseases in orthologs of genes with orthologous human diseases. We used Next Generation Sequencing in order to generate Whole Genome Sequences for 145 dogs from 69 different breeds with various inherited canine diseases, most of which were suspected to be inherited recessively. We here report the discovery of the causes of; Spinocerebellar Ataxia with Myokymia and Seizures in Russell-Group Terriers, Neuronal Ceroid Lipofuscinosis in Golden Retrievers and Dilated Cardiomyopathy in Standard Schnauzers. While all three were identified via whole genome sequencing, different methodologies and techniques were used to discover and validate the findings. We discuss the importance of these studies and suggest future studies for the projects as well as possible other means of discovering potential canine disease models via Whole Genome Sequencing. Summaries of these three findings are provided in the next three paragraphs. Juvenile-onset spinocerebellar ataxia has been recognized in Jack Russell Terriers and related Russell group terriers (RGTs) for over 40 years. Ataxia occurs with varying combinations of myokymia, seizures and other signs, thus more than one form of the disease has been suspected. Our objective was to identify the mutation causing the spinocerebellar ataxia associated with myokymia and/or seizures and distinguish the phenotype from other ataxias seen in the RGTs. We collected DNA samples from 16 RGTs with signs of spinocerebellar ataxia beginning from 2-to-12 months of age, 640 control RGTs, and 383 dogs from 144 other breeds along with the medical records of affected dogs in order to elucidate the genetic cause of this disease. Whole-genome sequencing was performed on one RGT with ataxia and myokymia. Unique, homozygous variants were identified in this dog by comparing its sequence to whole-genome sequences from 81 other canids. We found a missense mutation in the gene coding for the inward rectifying potassium channel Kir4.1 (KCNJ10:c.627C>G) that was significantly associated with the disease. Dogs homozygous for the mutant allele all showed spinocerebellar ataxia with varying combinations of myokymia, seizures and other signs. The identification of a mutation in KCNJ10 in dogs with spinocerebellar ataxia with myokymia and/or seizures (SAMS) clarifies the multiple forms of ataxia seen in these breeds and provides a DNA test to identify carriers. Understanding the role the Kir4.1 channel plays in extracellular potassium buffering by astrocytes could shed light on other conditions characterized by excessive neuronal membrane excitability such as other forms of ataxia, epilepsy and myokymia. We studied a recessive, progressive neurodegenerative disease occurring in Golden Retriever siblings with an onset of signs at 15 months of age. As the disease progressed these signs included ataxia, anxiety, pacing and circling, tremors, aggression, visual impairment and localized and generalized seizures. A whole genome sequence, generated with DNA from one affected dog, contained a plausibly causal homozygous mutation: CLN5:c.934_935delAG. This mutation was predicted to produce a frameshift and premature termination codon and encode a protein variant, CLN5:p.E312Vfs*6, which would lack 39 C-terminal amino acids. Eighteen DNA samples from the Golden Retriever family members were genotyped at CLN5:c.934_935delAG. Three clinically affected dogs were homozygous for the deletion allele; whereas, the clinically normal family members were either heterozygotes (n = 11) or homozygous for the reference allele (n = 4). Among archived Golden Retrievers DNA samples with incomplete clinical records that were also genotyped at the CLN5:c.934_935delAG variant, 1053 of 1062 were homozygous for the reference allele, 8 were heterozygotes and one was a deletion-allele homozygote. When contacted, the owner of this homozygote indicated that that their dog had been euthanized because of a neurologic disease that progressed similarly to that of the affected Golden Retriever siblings. We have collected and stored semen from a heterozygous Golden Retriever, thereby preserving an opportunity for us or others to establish a colony of CLN5-deficient dogs. Young-adult onset dilated cardiomyopathy (DCM) segregates in the Standard Schnauzer dog breed in a pattern consistent with an autosomal recessive mode of inheritance. To identify the molecular genetic cause of Standard Schnauzer DCM, DNA from an affected dog was used to generate a whole genome sequence with 31-fold average coverage. Among the sequence variants in this whole genome sequence was a 22-bp deletion and frameshift in RBM20, the canine ortholog of a gene previously associated with human DCM. The RBM20 deletion allele was homozygous in the whole genome sequence of the affected Schnauzer, but absent from 101 whole genome sequences of normal canids or dogs with other diseases. An additional 753 Standard Schnauzers, including 21 with DCM, were genotyped for the RBM20 deletion. In this cohort, all 20 of the deletion-allele homozygotes had DCM, only one of the 183 heterozygous dogs had DCM, and all of the reference-allele homozygotes were DCM free. RBM20 deficiency is known to alter exon-splicing patterns and produced aberrant titin isoforms in a rat model and in human DCM patients. To determine if the Standard Schnauzers with DCM had similar exon-splicing abnormalities, RNA prepared from their left ventricular walls was compared by RT-PCR to similarly prepared RNA from normal adult dogs. Titin transcripts with extensive exon skipping were detected in the normal RNA but not in the RNA from the dogs with DCM. Conversely, titin transcripts with retained exons were detected in the RNA from dogs with DCM but not in the normal-dog RNA. Thus, we have identified a canine model for human RBM20-associated DCM. While all three were identified via whole genome sequencing, different methodologies and techniques were used to discover and validate the findings. We discuss the importance of these studies and suggest future studies for the projects as well as possible other means of discovering potential canine disease models via Whole Genome Sequencing.

Available in PDF, EPUB and Kindle. Book excerpt: If you breed dogs for any reason, you must own this book. Genetic diseases are among the most serious hazards on the landscape of modern dog breeding and one of the most vexing challenges facing today's dog breeders. Is it appropriate to open the gene pool to unwanted conditions in the pursuit of physical perfection, or must breeding to the Standard take a back seat to producing healthy animals? In Control of Canine Genetic Diseases, renowned authority George A. Padgett, DVM, provides an expert road map to help dog breeders everywhere avoid the pitfalls they are almost destined to encounter. For anyone whose goal is to produce healthy, functional and beautiful dogs, this is the book they need. Dr. Padgett provides clear explanations of modes of inheritance, how to conduct and analyze test matings and how to lower the chances of producing affected animals. Numerous tables, diagrams and graphs further enhance the text to facilitate the breeder's understanding. A Howell Dog Book of Distinction
