Imputation of coding variants in African Americans: better performance using data from the exome sequencing project. Bioinformatics (Oxford, England). 2013 Nov 1;29(21). 2744-9. PMID: 23956302 [PubMed]. PMCID: PMC3799474.
Although the 1000 Genomes haplotypes are the most commonly used reference panel for imputation, medical sequencing projects are generating large alternate sets of sequenced samples. Imputation in African Americans using 3384 haplotypes from the Exome Sequencing Project, compared with 2184 haplotypes from 1000 Genomes Project, increased effective sample size by 8.3-11.4% for coding variants with minor allele frequency
