Putative candidate genes and their phenotype association in humans or animals based on OMIM [41] and OMIA [42] databases showing the number of variants detected in each of these genes in the Leonberger genomes. Leonberger University. Bioinformatics. The SNP genotyping data is available on reasonable request. In addition, the date of death was known for 4783 dogs (2453 females and 2330 males) born between 1959 and 2019. Boccardo et al. We thank Nathalie Besuchet-Schmutz and Heidi Signer-Hasler for invaluable technical assistance. ROH could be divided into five groups based on their size (Fig. Google Scholar. Only one missense variant in the DST gene was quite rare, i.e. Pedigree analyses based on extensive data revealed average litter size and life expectancy for the Leonberger dogs included in our study that are in agreement with previously reported results [52]. The Next Generation Sequencing Platform and the Interfaculty Bioinformatics Unit of the University of Bern are acknowledged for performing the WGS and providing high-performance computational infrastructure. The ROH-based genomic inbreeding coefficient (F_ROH) was on average 0.28 (ranging from 0.05 to 0.47). Because 33 of the 39 sequenced Leonberger individuals suffered from an unexplained form of polyneuropathy (see Additional file 1: Table S1), additional filtering was done for variants that were present in 113 putative candidate genes (see Additional file 2: Table S2) and could be involved in the development of the disease. The proportion of dogs belonging to the three groups that indicate the increasing relatedness to the whole population, is shown as green (MK < 0.31), yellow (MK = [0.310.32]), and orange (MK > 0.32) by country. The images or other third party material in this article are included in the article's Creative Commons licence, unless indicated otherwise in a credit line to the material. Private variants shared by all 39 Leonberger individuals and the rare variants that were present in at least one Leonberger individual were identified by comparison with the catalogue of variants in 605 publicly available control dogs from 128 various breeds and nine wolves provided by the Dog Biomedical Variant Database Consortium [24]. .

AL carried out the analyses, visualized the results, and drafted the manuscript. Johns Hopkins University. Panel (b) shows the continuously increasing population from 1979 to 2016. The short list of 21 potentially pathogenic variants in candidate genes for neurological disorders includes two previously reported variants: one in GJA9 that causes polyneuropathy [5] and one in NAPEPLD that causes leukoencephalomyelopathy [6]; these findings confirm the potential usefulness of the approach chosen. 2018;78:342131. These sequenced Leonbergers included four individuals that were sequenced to identify the pathogenic variants in the GJA9 and NAPEPLD genes described previously [5, 6]. The table shows the number of dogs for which the owners reported particular disorders. An amendment to this paper has been published and can be accessed via the original article. Annu Rev Cell Dev Biol. Front Genet. In addition, only biallelic SNPs on the 38 canine autosomes were retained for the ROH analyses and SNPs that deviated from the Hardy Weinberg equilibrium (p<0.0001) were excluded. . Popular sires are males that produced at least 33 puppies and account for 25% of all breeding males. a Average pedigree-based inbreeding coefficient and kinship estimated per year from 1920 to 2016. b Pie charts of the proportion of sires used in breeding clearly showing the popular sire syndrome. Genome-wide filtering of the WGS data revealed 28 non-protein-changing variants that were present in all Leonberger individuals and a list of 22 potentially pathogenic variants for neurological disorders of which 50% occurred only in Leonbergers and 50% occurred rarely in other breeds. The table includes detailed description and predictions of the biological consequences of the discovered variants on the corresponding proteins using different in silico prediction tools: PROVEAN [43], the MutPred suite (includes MutPred2 [44], MutPred-Indel [45], MutPred-LOF [46]), and PredictSNP [47]. Annu Rev Anim Biosci. a MDS plot of 1203 dogs showing no obvious subpopulations regardless of the geographical region of residence. In this case, an individual from the pointer breed that was homozygous for the wild type allele of SLC2A9 was used to produce unaffected heterozygous dogs, which were subsequently backcrossed to produce healthy individuals that are nearly indistinguishable from purebred Dalmatians [23].

The PLINK v1.9 software [35] was used to merge the genotype data and to perform quality control pruning and analyses of the runs of homozygosity (ROH). Most of the polyneuropathy-affected dogs (71.0%) showed both breathing and gait abnormalities, whereas for 14.6% only laryngeal paralysis or breathing problems, and for 14.4% only gait abnormalities were reported (see Additional file 5: Table S3). All rights reserved. 2006;6:812. PLoS Comput Biol. Subpopulations were expected due to the large geographic distances between the dogs: 579 samples (48.1%) came from the USA and Canada, 602 samples (50.1%) came from European countries, and 22 samples (1.8%) came from Australia, New Zealand, or Japan. The authors declare that they have no other competing interests. A recent survey conducted by the Leonberger Health Foundation International based on more than 1000 dogs from 24 countries also highlighted the high prevalence of certain forms of cancer such as osteosarcoma and hemangiosarcoma, as well as that of neurological disorders, such as laryngeal paralysis and other forms of polyneuropathy [60]. 2c), which indicates both old and recent inbreeding. Leonberger Health Foundation International. In addition, hypothyroidism was recorded quite frequently in our survey, confirming earlier reports for this breed [56, 57]. Google Scholar. The LCA has developed a custom presentation to train AKC Judges in the how to properly judge our breed. Other frequently seen groups of health issues included orthopaedic (15.8%), neurological (14.8%), endocrine (5.6%), digestive (4.2%), and cardiac (4.1%) problems. Furthermore, one of the two mtDNA haplogroups detected was present in one dog only. In addition, careful outcrossing might help optimize long-term genetic diversity, increase heterozygosity, and reduce the frequency of disease-causing alleles in order to lower the incidence of various health problems. The current lundehund population is highly inbred and optimal contribution selection alone results in no improvement due to the extremely high relatedness of the whole population [22]. Jagannathan V, Drgemller C, Leeb T. Dog Biomedical Variant Database Consortium (DBVDC). Historically, estimation of inbreeding has relied on in-depth pedigrees with inbreeding coefficients being estimated from pedigree-based relationships between ancestors (F_PED). Several in silico prediction tools, PROVEAN [43], MutPred2 [44], MutPred-Indel [45], MutPred-LOF [46], and PredictSNP [47], were used to predict the biological consequences of the discovered variants on the corresponding proteins. 2015;203:748. 2a) and (see Additional file 6: Figure S3), although a small group of North American dogs did not overlap completely with the rest of the population. This newly discovered GJA9 variant occurred at a quite high frequency (0.55) within the sequenced cohort of Leonberger dogs but was also comparatively common (frequency of 0.09) among the control dogs from 35 breeds (see Additional file 9: Table S5). Ekenstedt KJ, Becker D, Minor KM, Shelton GD, Patterson EE, Bley T, et al. 2004;101:1238790. Considerable genetic diversity has been lost in the Leonberger breed due to a bottleneck that occurred during the last century and to an increasing population size thereafter.

Breed-specific SNVs present at least in the heterozygous state in all Leonberger dogs and absent from the 614 control genomes. Integrative Genomics Viewer was used to visually inspect and confirm the detected SNVs [49]. Lampi S, Donner J, Anderson H, Pohjoismki J. The proportion of dogs with higher or lower MK differed between countries (see Additional file 4: Figure S2). Accessed 1 Jan 2020. The number of ROH per chromosome ranged from 1419 on chromosome 38 to 5303 on chromosome 1; the proportion of overall chromosomal regions involved in homozygous regions relative to chromosomal size was highest for chromosome 33 (16.9%) and lowest for chromosome 1 (6.6%) (Fig. 2017. https://doi.org/10.1101/134981. 2013;14:R132. In general, studies are based on SNP genotyping data of variable marker density and generally for less than 100 selected individuals per breed; e.g. A popular sire was defined as a male dog that sired at least 33 puppies, corresponding to five litters based on the observed average litter size. In addition, 10 SNVs were detected in the coding part of the mtDNA, among which seven were private, occurring rarely in individual Leonbergers and were not found in the 614 controls (see Additional file 12: Table S8). Privacy Animals. Mortlock SA, Williamson P, Khatkar MS. By using this website, you agree to our Similar studies could be performed in the Leonberger breed to unravel such associations and identify markers for selection against the elevated risk of developing certain forms of cancer. The WGS data of 39 Leonberger dogs including 38 individuals with variable neurological signs (see Additional file 1: Table S1) were compared to 614 publicly available canid WGS [24]. Inbreeding depression causes reduced fecundity in Golden Retrievers. the English greyhounds and Labrador retrievers that cluster based on specific working and show lineages or the Italian greyhounds and Shetland sheepdogs that form discrete clusters separating the European and North American populations [53]. Note that the number of dams is more or less as expected but the number of sires constantly decreases to about half of that of the dams in recent years, illustrating the popular sire syndrome. Ups J Med Sci. Ontiveros ES, Hughes S, Penedo MCT, Grahn RA, Stern JA. Its post-World War II popularity has resulted in a current global population of~30,000 dogs. Pagel KA, Pejaver V, Lin GN, Nam H-J, Mort M, Cooper DN, et al. Thus, the actual population size might be smaller since the current status for many animals was unknown.

The increasing size of the Leonberger population has been accompanied by a considerable loss of genetic diversity after the bottleneck that occurred in the 1940s due to the intensive use of popular sires resulting in high levels of inbreeding. Quantification of inbreeding due to distant ancestors and its detection using dense single nucleotide polymorphism data. Mamm Genome. The average pedigree-based inbreeding coefficient of 0.29 and average kinship of 0.31 show a dramatic loss of genetic diversity. BLAST-based comparisons of these loci revealed no significant sequence similarity to human genes. VJ performed bioinformatics. The average pedigree-based inbreeding coefficient (F_PED) and the average kinship showed a steady increase over the years analysed, with an estimated F_PED of 0.29 in the last cohort (year of birth 2016) (Fig. c Frequencies and counts of the different classes of ROH based on their length indicating both old and recent inbreeding. In addition, a slow continuous decrease across time was observed, from an average of 9.4years in 1989 to 7.7years in 2004 (median: 10.1 to 8.2years) (Fig. This cohort included 3044 dogs (1460 males and 1584 females) and revealed a mean of 8.2 (median 8.5) with the male longevity (mean=7.9) being on average lower than the female longevity (mean=8.5). When loss-of-function is loss of function: assessing mutational signatures and impact of loss-of-function genetic variants. The established mean kinship groups may also help breeders to select the most suitable mating pairs in addition to the already used pedigree-based inbreeding coefficients. An inbreeding coefficient based on ROH (F_ROH) was calculated as the total length of all ROH for one dog divided by the total length of the autosomal genome covered by SNPs. The exact number of records available per year is indicated in red above each year. Genomic DNA was isolated from blood using either the Gentra PureGene blood kit (Qiagen) or the Maxwell RSC whole blood DNA kit (Promega). In addition, the genealogical pedigree information was used to compare the estimated inbreeding coefficients and mean kinship in the current population. Pagel KA, Antaki D, Lian A, Mort M, Cooper DN, Sebat J, et al. The resulting identification of causative variants contributes to maintaining the sustainability of breeds by reducing the number of inherited health problems. 1c). 2019;15:e1007112.

Population size of the Leonberger breed between the years 19202016. Variant calling of single nucleotide and small indel variants (SNVs) was performed, and their functional effects were predicted based on the NCBI annotation release 105 as described in [24]. These data have been shown to be highly useful for the analysis of phenotypic variation [25] and for the identification of loci that contribute to both simple and complex disease susceptibility in dogs [26, 27]. We observed an average litter size across cohorts of 6.5 puppies and a constant generation interval of 4years. Genome-wide analyses implicate 33 loci in heritable dog osteosarcoma, including regulatory variants near CDKN2A/B. Lindblad-Toh K.

Ostrander EA, Wayne RK, Freedman AH, Davis BW. 1a). https://omim.org/. Written consent was obtained from all dog owners. MK of the current population was calculated for 31,832 selected dogs that were presumed to be available for breeding and alive at the time of calculation. Nine of these variants were located close to the detected ROH intergenic region on chromosome 26. Leonberger is a giant dog breed that was formed around the 1850s in Germany as a watch, companion, and family dog [1]. 3rd ed. Leo owners can also benefit from the resources linked at the bottom of this page. 2015;43:D777D78383. it was present in the heterozygous state in only one Howavart dog (see Additional file 9: Table S5). Pedigree information from 142,072 Leonberger individuals was available with a pedigree completeness index across five generations higher than 99% for the animals from the latest cohorts and exceeded 80% in 1935. 2015;19:1239. These sires are responsible for 66% of all offspring. Dog blood or cheek swab samples were obtained via elective owner submission for diagnostic purposes or were submitted for genotyping of the previously reported polyneuropathy-associated variants in Leonbergers. SNP genotype data analyses revealed a substantially low genetic diversity in the lundehund and therefore outcrossing with closely-related breeds was recommended to rescue the endangered population [13, 22].

Life expectancy was further evaluated for the period between 1989 and 2004 for which more than 100 records were available and we assumed that there were no more living dogs. The new genomic regions reported here might underlie breed-specific characteristics and provide information about the genetic structure of the breed, such as selection pressure on specific traits, inbreeding levels, or genetic bottlenecks. Forensic Sci Int. 2c). Our members will gladly spend time with you. 2017;33:i389i398398. The breed has predispositions to neurodegenerative disorders and cancer, which is likely due in large part to limited genetic diversity. Leonberger Health Questionnaire. PLoS One. In addition, the comparison between F_PED and F_ROH revealed a few dogs with obviously incorrect pedigree records and enabled the estimation of inbreeding in individuals with missing or unknown pedigrees (Fig. Karlsson EK, Sigurdsson S, Ivansson E, Thomas R, Elvers I, Wright J, et al. d Number of detected ROH per autosome (left y axis) and the proportion of chromosomes in a ROH (right y axis).

In other dog breeds, genetic association studies that aimed at identifying genetic risk factors [27] have revealed a strong association with specific genome regions, e.g. Kettunen A, Daverdin M, Helfjord T, Berg P. Cross-breeding is inevitable to conserve the highly inbred population of puffin hunter: the Norwegian Lundehund. Moreover, the MDS analysis did not show any clear differentiation based on geographical or purpose lineages in the Leonberger population, which contrasts with previous results in other breeds, e.g. Canine Med Genet. PLoS Comput Biol. 2e). In addition to a single missense variant predicted to be neutral, eight of the other nine variants were predicted as probably deleterious including two missense, two frameshift, two in-frame-insertions, one in-frame-deletion, and one nonsense variant (Table 1) and (see Additional file 9: Table S5 and Additional file 10: Table S6). Mutations in the SLC2A9 gene cause hyperuricosuria and hyperuricemia in the dog. All authors read and approved the final manuscript. Livest Sci. https://omia.org/. This is also reflected in panel (c), where the dogs are coded by their calculated MK coefficient, which was not determined for the older dogs.
