Count of variants identified using the GRCh37 and GRCh38 references in each sample
(A and B) Distributions of variant count in each sample (A for SNV and B for indel), grouped by genetic ancestry of the individuals.
(C and D) Distribution of variant count differences between GRCh37 and GRCh38 in each sample (C for SNV; D for indel). The red line shows the median difference across all samples.
Note that the variant counts shown here include variants in exons and regions within 100 bp to exon boundaries (EAS, East Asian; AMR, admixed American; EUR, European; SAS, South Asian; AFR, African American).
