Figure 2From: Properties of permutation-based gene tests and controlling type 1 error using a summary statistic based gene testPower for permutation-based gene test as a function of causal SNP’s location relative to correlated region and effect size. There is more power to detect a SNP in high LD with other, non-causal SNPs (solid, black line), than a SNP in low LD (dashed, blue line) for an identical effect size.Back to article page
