While low MAF SNPs (1% or 5%) did not have elevated false positives compared to chance, the 5% MAF SNPs had significantly more false positives than the more common (25 and 50%) MAF SNPs at the 10-4 (p < 0.03) and 10-5 (p < 0.05)thresholds. These differences were not captured by standard summary statistics, but instead, only by examining values at the tail end of the distribution.
