GWAS was performed on 815 children from 263 Hispanic families. Mean ± SD (range) was 25.2±7.5 (13.4 to 61.9) for the children’s BMI, 85.6±20.8 (4 to100) for BMI percentile and 1.52±1.01 (−3.0 to 4.5) for BMI z-score. Measured genotype analysis examined 129 obesity-related traits including BMI and adiposity as well as biological processes associated with the pathophysiology of childhood obesity; a description of the phenotypes is provided in Table S1. In our GWAS, population stratification was not significant and therefore did not confound our associations. A complete listing of all suggestive (p<1.0E-06) and genome-wide significant (p<1.0E-07) genetic variants and their associated traits are presented by chromosomal position in Table S2.
