In our cohort of extended Northern European families, the Metabolic Risk Complications of Obesity Genes (MRC-OB) cohort, transcript levels of FABP3 from peripheral white blood cells (PWBCs) has been found to be suggestively correlated (p<0.1) with the MetS key axis phenotype defined by the two leading components waist circumference (WC) and homeostasis model assessment (HOMA) (unpublished data) [2,18-20]. This evidence concerns the gene FABP3 and metabolic syndrome.
