Background Classical bovine spongiform encephalopathy (BSE) is an acquired prion disease that is invariably fatal in cattle and has been implicated as a significant human health risk. Polymorphisms that alter the prion protein of sheep or humans have been associated with variations in...

Gene duplications are common in the vertebrate genome, and duplicated loci often show a variation in copy number that may have important phenotypic effects. Here we describe a powerful method for quantification of duplicated copies based on pyrosequencing. A reliable quantification was obtained...

An Assessment of Population Structure in Eight Breeds of Cattle Using a Whole Genome SNP Panel
Download2008
Schnabel, R. D., Wang, Z., Taylor, J. F., Gill, C. A., Van Tassell, C. P., Gao, C., Aerts, J., Williams, J. L., Neto, E. D., Murdoch, B. M., Matukumalli, L. K., Coppieters, W., McKay, S. D., Mannenl, H., Crews, D., Moore, S. S.
Background Analyses of population structure and breed diversity have provided insight into the origin and evolution of cattle. Previously, these studies have used a low density of microsatellite markers, however, with the large number of single nucleotide polymorphism markers that are now...

Association of a missense mutation in the bovine leptin gene with carcass fat content and leptin mRNA levels
Download2002
Fitzsimmons, C. J., Thue, T. D., Buchanan, F. C., Winkelman-Sim, D. C., Schmutz, S. M., Van Kessel, A. G.
Previously, we have shown that alleles of the BM1500 microsatellite, located 3.6 kb downstream of the leptin gene in cattle, were associated with carcass fat measures in a population of 154 unrelated beef bulls. Subsequently, a cytosine (C) to thymine (T) transition that encoded an amino acid...

Dominant Red Coat Color in Holstein Cattle Is Associated with a Missense Mutation in the Coatomer Protein Complex, Subunit Alpha (COPA) Gene

Sällman Almén, M., Liao, X., Stothard, P., Henegar, C., Van Doormaal, B., Rubin, C. -J., Andersson, L., Barsh, G. S., Ito, S., Plastow, G., Wakamatsu, K., Dorshorst, B.
Coat color in Holstein dairy cattle is primarily controlled by the melanocortin 1 receptor (MC1R) gene, a central determinant of black (eumelanin) vs. red/brown pheomelanin synthesis across animal species. The major MC1R alleles in Holsteins are Dominant Black (MC1RD) and Recessive Red (MC1Re). A...

Kolbehdari, D., Stothard, P., Schnabel, R., Wang, Z., Marques, E., Taylor, J. F., Moore, S. S.
Background Linkage disequilibrium (LD) maps can provide a wealth of information on specific marker-phenotype relationships, especially in areas of the genome where positional candidate genes with similar functions are located. A recently published high resolution radiation hybrid map of bovine...

Xu, J., Goebel, R. A., Cai, Z., Sabaai, H., Lin, G., Wang, Z., Wang, Y., Stothard, P.
Background The \"common disease – common variant\" hypothesis and genome-wide association studies have achieved numerous successes in the last three years, particularly in genetic mapping in human diseases. Nevertheless, the power of the association study methods are still low, in particular on...

Background Bovine whole genome linkage disequilibrium maps were constructed for eight breeds of cattle. These data provide fundamental information concerning bovine genome organization which will allow the design of studies to associate genetic variation with economically important traits and...
