Witryna13 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 …
Genotype imputation for genome-wide association studies
WitrynaGenotype imputation has become a standard tool in genome-wide association studies because it enables researchers to inexpensively approximate whole-genome sequence data from genome-wide single-nucleotide polymorphism array data. Genotype imputation increases statistical power, facilitates fine mapping of causal variants, and … Witryna1 paź 2024 · The imputation methods based on the Li and Stephens model consider phased genotypes obtained using SNP array or other genotyping technologies as input genotype data, and estimate the haplotypes that match with the input genotype data by considering the recombinations of haplotypes present in the haplotype reference panel. cigar bars in georgetown
Genotyping, characterization, and imputation of known and novel
WitrynaOther poorly imputed genomic regions and the number of SNPs in those regions are presented in Table 8. Such intrinsically difficult-to-impute genomic regions have also … 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.
