The logistic regression model showed that when obesity was classified based on BFP, it was associated with eight SNPs in GPX3, GPX4, and PON1; however, the association remained in only one of them and was marginally significant for another one after Bonferroni adjustment: GPX4 rs2074451 and GPX3 rs922429, respectively. This evidence concerns the gene GPX4 and obesity due to melanocortin 4 receptor deficiency.
