It can effectively boost the power of detecting single nucleotide polymorphisms (SNPs) in genome-wide association studies, integrate multi-studies for meta-analysis, and be applied in fine-mapping studies. The …

Witryna2 dni temu · More generally, with a GWAS summary dataset of a trait, we can impute the trait values for a large sample of genotypes, which can be useful if the trait is not available, either unmeasured or difficult to measure (e.g. status of a late-onset disease), in a biobank. We propose 2 Jo rna l P re- pro of a nonparametric method for large …
Witryna17 lip 2013 · Genotype imputation is a common and useful practice that allows GWAS researchers to analyze untyped SNPs without the cost of genotyping millions of additional SNPs. In the Services Department at Golden Helix, we often perform imputation on client data, and we have our own software preferences for a variety of reasons. … Witryna1 lis 2015 · Genotype imputation methods like Beagle and fastPHASE use a similar reasoning: they use information from neighboring SNPs because these SNPs likely share a history with the SNP to be imputed due to physical linkage. Beagle and fastPHASE rely, however, on ordered markers and sufficiently dense genotype data to enable …

Imputation in genetics refers to the statistical inference of unobserved genotypes. It is achieved by using known haplotypes in a population, for instance from the HapMap or the 1000 Genomes Project in humans, thereby allowing to test for association between a trait of interest (e.g. a disease) and … Zobacz więcej In genetic epidemiology and quantitative genetics, researchers aim at identifying genomic locations where variation between individuals is associated with variation in traits of interest between individuals. Such studies hence … Zobacz więcej There are several software packages available to impute genotypes from a genotyping array to reference panels, such as 1000 Genomes Project haplotypes. These tools include MaCH Minimac, IMPUTE2 and Beagle. Each tool provides specific pros … Zobacz więcej Genotyping arrays used for genome-wide association studies (GWAS) are based on tagging SNPs and therefore do not directly genotype all variation in the genome.
