O-36: Genome Haplotyping and Detection of Meiotic Homologous Recombination Sites in Single Cells, A Generic Method for Preimplantation Genetic Diagnosis
Background: Haplotyping is invaluable not only to identify genetic variants underlying a disease or trait, but also to study evolution and population history as well as meiotic and mitotic recombination processes. Current genome-wide haplotyping methods rely on genomic DNA that is extracted from a large number of cells. Thus far random allele drop out and preferential amplification artifacts of...
متن کاملA model of higher accuracy for the individual haplotyping problem based on weighted SNP fragments and genotype with errors
MOTIVATION In genetic studies of complex diseases, haplotypes provide more information than genotypes. However, haplotyping is much more difficult than genotyping using biological techniques. Therefore effective computational techniques have been in demand. The individual haplotyping problem is the computational problem of inducing a pair of haplotypes from an individual's aligned SNP fragments...
متن کاملMinimum Conflict Individual Haplotyping from SNP Fragments and Related Genotype
The Minimum Error Correction (MEC) is an important model for haplotype reconstruction from SNP fragments. However, this model is effective only when the error rate of SNP fragments is low. In this paper, we propose a new computational model called Minimum Conflict Individual Haplotyping (MCIH) as an extension to MEC. In contrast to the conventional approaches, the new model employs SNP fragment...
متن کاملHaplotyping and estimation of haplotype frequencies for closely linked biallelic multilocus genetic phenotypes including nuclear family information.
With the discovery of single nucleotide polymorphisms (SNP) along the genome, genotyping of large samples of biallelic multilocus genetic phenotypes for (fine) mapping of disease genes or for population studies has become standard practice. A genetic trait, however, is mainly caused by an underlying defective haplotype, and populations are best characterized by their haplotype frequencies. Ther...
متن کاملModels and Algorithms for Haplotyping Problem
One of the main topics in genomics is to determine the relevance of DNA variations with some genetic disease. Single nucleotide polymorphism (SNP) is the most frequent and important form of genetic variation which involves a single DNA base. The values of a set of SNPs on a particular chromosome copy define a haplotype. Because of its importance in the studies of complex disease association, ha...
