As G/A polymorphism in exon 3 of the FATP4 genes rise to a Gly209Ser substitution with potential structural-functional implications, a group of researchers investigates whether variation within the FATP4 gene influences fasting and postprandial lipid and lipoprotein variables along with markers of insulin resistance (IR) in healthy, middle-aged Swedish men (Gertow et al., 2004). The gene discussed is SLC27A4; the disease is Insulin resistance.
