Previous genome-wide association studies (GWASs) have identified several loci associated with human height; however, such evidence was mostly reported in Caucasian populations. Since the different distributions of height between populations suggest their different genetic backgrounds, analysis in different populations would be useful. Here, we present the results of a GWAS for adult height in 19 633 Japanese subjects. We found eight significantly associated loci that satisfied the genome-wide significance level (P < 5.0 × 1028). Of these, the association to the LHX3-QSOX2 locus was entirely novel (rs12338076, P = 2.2 × 10-8 We also identified the association to the IGF1 locus (rs17032362, P = 8.1 × 10-9 Conditional association analysis in the IGF1 locus with rs17032362 suggested the existence of an additional independent association with height to this locus (rs1457595, P = 1.2 × 10-5 We observed large differences in the allele frequencies of rs17032362 and rs1457595 between Japanese (34 and 9%, respectively) and Caucasian (1.7 and 0%, respectively) populations, thereby suggesting weak statistical powers for the IGF1 locus in the previous Caucasian GWASs for height. We extensively compared our results with those of previous reports on the Caucasian and Korean populations. We were able to replicate all four loci previously reported in Koreans (EFEMP1, ZBTB38, HMGA1 and PLAG1, P < 5.0 × 10-8) and 15 loci identified in Caucasians (P < 0.001). The combination of the height-associated loci identified in our study and the previous GWASs demonstrated an effect size of 1.26 cm (95% confidence interval: 1.18-1.34) per 1.0 increase of the normalized Z score for height-increasing alleles, explaining 4.6% of the total variance of adult height.
