We detected 29 novel variants. Seven of these have also been reported by other groups while we were validating our sequencing results. While many of these were rare (MAF≤5%), ten had MAF ≥ 10% based on the 44 chromosomes. We genotyped these novel variants in the original 1608 EAs. Eleven were polymorphic in this larger sample and passed quality control (per-SNP call rate ≥ 0.96 and Hardy-Weinberg p ≥ 0.05).
