Fig. 3From: A new strategy for enhancing imputation quality of rare variants from next-generation sequencing data via combining SNP and exome chip dataMean estimated r 2 of various combinations of reference panels and genotype panels. Reference panels are the 1000 genomes phase 1 dataset (1KG) and various combinations of whole exome sequencing data (WES), SNP chip data (GWAS), and exome chip data (EXOME)Back to article page
