Imputed variants
Witryna23 lip 2024 · It has been claimed by some studies that it is unattainable to impute rare variants with MAF <0.03 (17), whereas some other studies have indicated that it is possible to impute not only “less common” variants, but even rare and “very rare” (MAF <0.01) variants using GWAS data (18,19). Witrynacalculated between the allele dosages at variants in each bin with the masked CG genotypes. Since different arrays contain different numbers of variants it is important to make sure that imputation performance is measured at the same set of variants when comparing chips. To achieve this, both imputed and array variants were included
