After data cleaning, results were obtained for 8,458,542 polymorphisms (Figure 1). The marker rs193135937 on chromosome 4 had a p-value of 1.28 × 10−8, surpassing the genome-wide significance threshold (3.06 × 10−8 for imputed data [45]). The q-value for rs193135937 was 0.11. This intergenic SNP is >500kb downstream from the pseudogene LOC100288337. No surrounding markers approached this significance level. No other markers achieved genome-wide significance. The QQ-plot is depicted in Figure 2. The genomic inflation value was λ=1.015 (SE=3.031 × 10−6).
