We computed values of D' for the significantly associated SNPs on chromosomes 2 and 7 (Tables 1 and 2). Thus, we focused on chromosome 7 because multiple significant SNPs were detected there. An LD block extended from 124.757 Mb to 124.791 Mb, covering the three most significantly associated SNPs; in fact, this block satisfied |D'| ≥ 0.9 for all marker pairs. Thus, the evidence for association in this region does not come from three independent SNPs but rather indicates a single LD block associated with the phenotype.
