The differences between SSc and control groups in other markers of intestinal permeability, i.e., IFABP and claudin-3, were not statistically significant: IFABP (1505.0 pg/mL [1108.0–1865.0] versus 1598.0 pg/mL [921.8–1835.0], p = 0.45); claudin-3 (14.44 ng/mL [11.85–94.53] versus 15.22 ng/mL [11.83–23.11], p = 0.63). The gene discussed is FABP2; the disease is systemic sclerosis.
