For gene-based collapsing, rare variants were selected for further analysis if they were available in the true dataset, the exome array data. Rare variants of true data set were also collapsed using collapsing and collapsing based on haplotypes for PostC and PreCimp, respectively. To measure imputation accuracy, we used dosage r2 that is squared Pearson correlation between imputed dosages and true genotypes.
