WitrynaImputation can help improve genomic coverage, facilitate comparison and combination of studies that use different marker panels, increase the power to detect genetic associations by combining datasets from different studies, and guide fine-mapping of quantitative trait loci. Witryna2 cze 2010 · Genotype imputation can be carried out across the whole genome as part of a genome-wide association (GWA) study or in a more focused region as part of a …
Witryna25 maj 2024 · To evaluate the performance of imputation with the reference panels, the accuracy of imputed genotypes was assessed by a five-fold CV for the haplotype panels that were constructed with over 100 samples (Table 2 ). In each test round, samples of each species were divided into five groups. Witryna14 kwi 2024 · Human genomics has quickly evolved, powering genome-wide association studies (GWASs). SNP-based GWASs cannot capture the intense polymorphism of HLA genes, highly associated with disease susceptibility. There are methods to statistically impute HLA genotypes from SNP-genotypes data, but lack of …
WitrynaGenotype imputation increases statistical power, facilitates fine mapping of causal variants, and plays a key role in meta-analyses of genome-wide association studies. Only variants that were previously observed in a reference panel of sequenced individuals can be imputed. WitrynaGenomics ⏵ Imputation Description Imputed genotype and phased haplotype values. Genotypes were imputed into the dataset using computationally efficient methods …
