Witryna19 cze 2024 · Simulation studies showed that 98% of WGS-based GWAS hits fell within 100 kb of the causal variants with a minor allele frequency <0.01, whereas only 68% met the criteria for 1KGP3-based imputation. Underlying this finding is the fact that most of the rare variants in the 1000 UK Genomes study were not present in the imputation … Witryna10 lis 2024 · The use of large reference and target panels improves the accuracy of the imputed genotypes and provides genotypes for more markers segregating at low frequency for downstream genomic analyses.
