Other protein coding genes involved in UTR fusions in our cancer samples that have been previously associated with cancer onset and/or progression are the interferon gamma receptor 1 (IFNGR1) gene [63], the period circadian clock 2 (PER2) gene [64, 65], the chloride intracellular channel 4 (CLIC4) gene [66], the sorbin and SH3 domain containing 2 (SORBS2) gene [67] and the eukaryotic translation initiation factor 2-alpha kinase encoding (EIF2AK2) gene [68, 69]. The gene discussed is PER2; the disease is cancer.
