EP300 and neoplasm: Given that the fundamental oncogenic process of HPV infection features viral oncoproteins E6 and E7 interfering with the function of p53 and Rb proteins, respectively [18], it was not entirely unexpected that the genomic sequencing of our patient’s HPV-related tumor did not reveal mutations in TP53 and RB1. Notably, the cancer was positive for mutations in CREBBP and EP300. These observed alterations together are consistent with and provide a potential molecular basis for the small cell phenotype seen in our case.
