p-values were calculated using PLINKs′ adaptive permutation procedure with 106 permutations.
Displayed are the SNPs included in the three best haplotypes (Table 1) for the explored genomic region surrounding the melanocortin 4 receptor gene (MC4R, location: chromosome 18: 55,879,013–56,243,921 bps). The obesity-predisposing allele (obesity effect allele) within each sample is highlighted in bold.
