PVT1 and ovarian cancer: It is also possible that this region may harbour a long range enhancer for MYC and/or PVT1 or there may be an uncharacterised genetic element in this region that has an additional independent oncogenic effect to that of MYC or PVT1. This peak feature has not been previously appreciated in the somatic genetics of ovarian cancer, and its detection is a consequence of having a large number of samples at high resolution copy number coverage.
