PPARG and obesity due to melanocortin 4 receptor deficiency: A comparison of obesity/anthropometry parameters between subjects with concomitant presence of variant alleles and those with wild-type alleles was conducted for those three genotypes included in the study (PPARG rs1801282, PPARG rs3856806, and PPARGC1A rs8192678) in which an important prevalence of the variant allele was encountered.
