SNPs that reached genome-wide significance (P−8) in the combined analysis.

For loci with more than one SNP with a P−8, we list the SNP with the smallest combined P-value. Results for the 153 SNPs that were followed up by in silico replication are available in Table S2. We highlight in bold the two loci not previously implicated in the regulation of height in European-ancestry populations. Effect size (beta) and standard error (SE) are in Z-score units. The effect allele frequency is the average frequency across all African-American discovery studies. The heterogeneity P-value is based on Cochran Q heterogeneity test. I2 is a measure of heterogeneity and represents the proportion of inconsistency in individual studies that cannot be explained by chance.
