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 experimentally untyped genetic variants, but whose genotypes have been statistically inferred ("imputed"). Genotype imputation is usually performed on SNPs, the most common kind of gene… WitrynaTo mimic a typical imputation analysis, a pseudo-GWAS dataset was constructed by extracting the CG SNP genotypes at all the sites included on a given array.
