Recent TCGA genomic classifications of high-grade serous ovarian adenocarcinoma and endometrial carcinomas revealed high levels of somatic CNAs in high grade serous ovarian and serous endometrial tumors, including recurrent amplifications in MYC, and CCNE1. We observed fewer CNAs in non-serous ovarian tumors, including only 2 samples with a MYC amplification and no samples with a CCNE1 amplification. Here, CCNE1 is linked to ovarian serous adenocarcinoma.
