Table 1 Distributions of the number of causal SNPs significantly correlated (r_τ_j > 0.1) with each SNP

Data set	Number of correlated (r_τj > 0.1) causal SNPs
	0	1	2	3	4	5	6	7	>7
GAW17	13,288	5,153	2,402	870	424	278	136	85	121
Simulated data	14,322	5,229	2,092	729	245	104	29	7	0

For each SNP in the GAW17 data and in the simulated data, we count how many of the 39 causal SNPs in the GAW17 data have correlation coefficients r_τj > 0.1 with it. We find that 9,469 SNPs in the GAW17 data and 8,435 SNPs in the simulated data are correlated (r_τj > 0.1) with at least one causal SNP. Note that in the simulated data set, all SNPs are simulated to be in linkage equilibrium with each other and with the 39 causal SNPs, so all observed correlations are due to chance alone.
