SOD2 and chronic granulomatous disease: The differences in expression between the X-PLB monocytes and PLB monocytes (SOD2; 2.56 ± 0.44, n = 3 and TXN; 1.35 ± 0.09, n = 3, fold higher expression in X-PLB monocytes) were strikingly similar in magnitude to those observed in our microarray analysis of differential gene expression between the primary CGD and control monocytes.
