The resulting heatmap revealed a cluster of genes (cluster 2) with markedly higher expression in sepsis samples compared to healthy samples, including S100 calcium-binding protein A12 (S100A12), interferon-induced transmembrane protein 2 (IFITM2), nuclear enriched abundant transcript 1 (NEAT1) and Fc epsilon receptor Ig (FCER1G) (Fig. 4a). The gene discussed is FCER1G; the disease is Sepsis.
