Genotype imputation是什么
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… WebApr 7, 2024 · Genotype imputation is the process of predicting unobserved genotypes in a sample of individuals using a reference panel of haplotypes.
