To examine differentially expressed genes in FLC, we performed RNA-seq on an expanded set (Cohort 1) of FLC patient tumors (n = 35) and matched non-malignant liver (NML, n = 10) from the Fibrolamellar Cancer Foundation biobank, and confirmed DNAJB1-PRKACA (DP fusion) expression in all tumor samples. The gene discussed is DNAJB1; the disease is neoplasm.
