Detection of a recurrent DNAJB1-PRKACA chimeric transcript in fibrolamellar hepatocellular carcinoma

This study was the first published research effort that identified the DNAJB1-PRKACA chimeric transcript in fibrolamellar carcinoma tumors. By performing RNA sequencing on tumor and healthy tissue samples, a chimeric transcript was discovered that had not been previously reported in the literature. This fusion transcript arises due to a ~400-kilobase deletion on chromosome 19. In …

The genomic landscape of fibrolamellar hepatocellular carcinoma: whole genome sequencing of ten patients

This study sequenced the DNA from FLC tumors and compared the results to the DNA from non-cancerous tissue from the same patients to identify the specific mutations that had occurred in the cancer. In the 10 samples examined, the only consistent mutation was the DNAJB1-PRKACA fusion gene. Since the only consistent mutation found was the …
