Fig. 1

Chromosome 6p21.3 polymorphisms discovered in three NPC GWASs. Top: The triangles indicate the P values reported by the GWASs on a negative logarithmic scale according to the chromosome locations of the SNPs. Red: Tse [16]; Green: Bei [17]; Blue: Tang [18]. The solid triangles indicate the SNPs used in the meta-analysis. The hollow triangles indicate the other SNPs listed in the GWASs. Bottom: Detailed LD structure depicted in HaploView by using control samples from the NPC GWAS in Taiwan [16]. The increasing intensities of red represent lower D’ values
