Matching of 1000 Genomes data with reference alleles. (A-C) Matching 1000G data with reference allele data for 43 blood group genes. (A) Total number of alleles and (B) unique alleles in the 1000G that were successfully matched or not matched to the entries in any of the reference data. A majority of all alleles but only a minor proportion of the unique alleles were matched, suggesting that common alleles were successfully matched while rare alleles were not. (C) Total number of nonsynonymous CDS variants that were found in the reference data. Only a minor proportion of the variants were listed in the reference data. (D-E) Number of alleles and variants in the reference allele data that could be matched to 1000G data. (D) Total number of alleles in the reference data that could be matched or not matched to 1000G data. Not matchable alleles are alleles that contain unmatchable variants. (E) Total number of alleles in the reference data that could be matched or not matched to 1000G data. Not matchable variants are rearrangements, hybrid alleles, and indistinctly defined variants.
