We identified a novel in-frame BRD4-NUTM1 fusion in SBC-3, a cell line established from a 24-year-old male diagnosed with small-cell lung carcinoma (SCLC)34, and confirmed the fusion by Sanger sequencing and FISH (Fig. 5a, b and Supplementary Fig. 4a). The gene discussed is BRD4; the disease is small cell lung carcinoma.
