Figure 5From: Properties of permutation-based gene tests and controlling type 1 error using a summary statistic based gene testPower comparison for summary statistic test when causal SNP is in an LD block versus not in an LD block. A SNP in high LD with other, non-causal SNPs (solid, black line), has no more power to be detected with the summary statistic test than a SNP in low LD (dashed, blue line).Back to article page
