PBS distribution of representative genes in GO term “camera-type eye development” and “visual perception.” A, B, and C illustrate the physical position-dependent distribution of the population branch statistics (PBS) within a 2-kb window upstream and downstream of the ARL6, RPGGRIP1L, and MED1 coding region, respectively. PBS values were calculated using the FIN, TSI, and YRI populations. Circles and colors represent allele frequencies and P-values of each SNPs, respectively, in a previous myopia GWAS in Europeans [21]. FIN, Finnish in Finland; TSI, Toscani in Italy; YRI, Yoruba in Ibadan, Nigeria
