after only the first GC correction (see Supplementary Table 2) because a second GC correction is generally considered to be over-conservative32. We additionally selected SNP rs6537307 (P=4.3×10−5), which is in linkage disequilibrium with a known HHIP height-associated variant (HapMap r2 = 0.58 with rs685478333). Of the 22 selected SNPs, rs1004059 at SYNP02L (P = 2.3×10−6) was available in only 8 studies since its MAF was close to 0.01. After obtaining data from this SNP from all available Stage 1 studies, we observed a meta-analysis P-value of P = 6×10−5, and so did not consider it further.
