Gene expression analysis of patient PBMCs reveals alterations in IFN-regulated genes and multiple signaling pathways. (A) Heat map of baseline gene expression of a custom Nanostring gene set in PBMCs of four G207E patients, a Singleton-Merten syndrome patient (SMS-pat; another type I interferon-mediated disease), and three healthy controls. After background thresholding and normalization, agglomerative clustering was performed on z-scores of genes. IFN-regulated genes are marked in red. (B) mRNA fold changes of seven IFN-regulated genes (IFIT1, ISG15, RSAD2, SICLEC1, IFI27, IFI44, and IFI44L) and the resulting IFN score for each patient. (C–E) Fold changes in unstimulated patient PBMCs of inflammasome (C), JAK/STAT pathway (D), and NFκB pathway (E) related genes. Fold change 1 and 4 are indicated with green and blue dotted lines, respectively. Through (A–E) mean of three measurements together with SD is presented.
