FKBP5 gene expression levels positively correlated with markers of insulin resistance, including the glucose area under the curve (AUC) during OGTT (r = 0.33, p < 0.05), fasting glucose (r = 0.47, p < 0.01), Quantitative Insulin Sensitivity Check Index (QUICKI; r = -0.33, p<0.05) and HOMA-IR (r = 0.34, p < 0.05). This evidence concerns the gene FKBP5 and Insulin resistance.
