Extended Data Table 1 | Imputation accuracy for C4 copy numbers in European ancestry and African American haplotypes
Imputation accuracy was evaluated by correlation of imputation results to C4 gene copy numbers directly inferred from WGS data. Aggregated copy numbers imputed from each round of
leaving ten individuals out were correlated with the directly-typed measurements and are reported as r^2 for each feature of C4 structural variation for European ancestry (693 individuals) and
African American (250 individuals) members of the reference panel separately.
