IER2 and bathing suit ichthyosis: Three genes had increased levels of expression in S. aureus BSI patients: Cd97 (1.16-fold, p<0.05), Crif1(1.87-fold; p<0.0001), and Hook2 (1.29-fold, p = 0.0001), while other candidate genes were significantly down-regulated (Ier2: 0.93-fold, p<0.05; Rnaseh2a: 0.80-fold, p = 0.001; Tbc1d9: 0.82-fold, p<0.001; Lyl2: 0.72-fold, p<0.001; Farsa: 0.66-fold; p<0.0001; Inpp4b: 0.54-fold; p<0.0001; and Tnpo2: 0.84-fold; p<0.0001).
