Candidate region screening. The x- and y-axes represent the specific chromosome position and –log10P value, respectively. a Comparison between the GWAS on chromosome 4 and conditional GWAS after removing the effect of the most significant SNP. After integrating the genotype of Chr. 4: 10,180,939 bp into the analysis as a covariate, all of the remaining SNPs lost significance. b LD analysis in the region with significant SNPs. R2 > 0.2 was considered to indicate linkage. A ~ 167 kb LD block was confirmed, and there were also several independent small-range LD blocks within this region. c Genes within the 167 kb LD block
