The nuclear receptor PPARgamma is important for biological processes including adipogenesis and glucose homeostasis. In subjects with severe insulin resistance, we have previously reported two types of human PPARgamma gene defect: heterozygous, missense mutations (P467L, V290M) in the ligand binding domain (LBD) which inhibit wild type (WT) receptor action in a dominant negative manner by recruitment of transcriptional corepressors; or double heterozygosity for a frameshift/pr...
