The much-anticipated fixed-array, genome-wide SNP genotyping technologies make large-scale genome-wide association scans now possible for large numbers of subjects. In this paper we reconsider the problem (Satagopan and Elston [2003] Genet Epidemiol 25:149-157) of optimizing a two-stage genotyping design to deal with important new issues that are relevant when studies are expanded from candidat...
PURPOSE Studies in relatives have generally yielded high heritability estimates for refractive error: twins 75-90%, families 15-70%. However, because related individuals often share a common environment, these estimates are inflated (via misallocation of unique/common environment variance). We calculated a lower-bound heritability estimate for refractive error free from such bias. METHODS Bet...
Homer and others (2008. Resolving individuals contributing trace amounts of DNA to highly complex mixtures using high-density SNP genotyping microarrays. PLoS Genetics 4, e1000167) recently showed that, given allele frequency data for a large number of single nucleotide polymorphisms in a sample together with corresponding population "reference" frequencies, by typing an individual's DNA sample...
In wheat, a lack of genetic diversity between breeding lines has been recognized as a significant block to future yield increases. Species belonging to bread wheat's secondary and tertiary gene pools harbour a much greater level of genetic variability, and are an important source of genes to broaden its genetic base. Introgression of novel genes from progenitors and related species has been wid...
Recently, structural variation in the genome has been implicated in many complex diseases. Using genomewide single nucleotide polymorphism (SNP) arrays, researchers are able to investigate the impact not only of SNP variation, but also of copy-number variants (CNVs) on the phenotype. The most common analytic approach involves estimating, at the level of the individual genome, the underlying num...
The Single Nucleotide Polymorphisms (SNP) Discovery on Transcriptome of Pure Sistani and Cross-Breeding Holstein, Simmental Monte Billiard Bulls
Background: Congenital factor XIII (FXIII) deficiency is one of the rarest bleeding disorders with a prevalence of one per 2 million in the general population. The disorder is accompanied by a high rate of life-threatening bleeding. Due to normal results of routine coagulation tests, diagnosis of the disorder is challenging, but molecular methods can be used for precise diagnosis. Direct mutati...
the growth hormone (gh) gene is a candidate for growth trait in farm animals and plays an important role in growth metabolism. growth hormone can contribute in growth metabolism when it's receptor (ghr) are on cells target. the single nucleotide polymorphism was occurred in gh and ghr genes and that associated with carcass traits in lori-bakhtiari sheep breed with using pcr-sscp. in this r...
