Witryna26 sty 2015 · This metric typically takes values between 0 and 1, where values near 1 indicate that a SNP has been imputed with high certainty. The info metric is often used to remove poorly imputed SNPs from the association testing results. Different thresholds were recommended for different MAF categories. Witryna12 mar 2024 · One of the main issues in imputing sequence from low- or even high-density SNP panels in any population is the huge number of SNPs that have to be imputed. The accuracy of imputation tends to decrease as the number of SNPs from the lower density SNP panel decreases.
Witryna10 lis 2014 · In our GWAS, we used the allelic dosages of these SNPs, which are individuals’ posterior expected reference-allele counts on each SNP so imputed. The quality of the imputation for an untyped SNP may be assessed by its imputation R 2, which is the ratio of the variance of its imputed dosages to its population variance … 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.
