IREB2 and small cell lung carcinoma: We reduced the number of eQTLs to unique target genes (see “Methods”) and found no genes that overlapped all three subtypes, no genes that overlapped LUAD and SCLC, two genes that overlapped LUSC and SCLC in one genomic region (MYL4 and RPRML), and one gene (IREB2) that overlapped the two NSCLC subtypes (Fig. 2d).
