MRPL15 and ovarian serous cystadenocarcinoma: We analyzed the correlation between MRPL15 expression in ovarian cancer and four levels of copy number variation (single‐copy deletion, diploid normal copy, low‐level copy number amplification, and high‐level copy number amplification) using data from TCGA Ovarian Serous Cystadenocarcinoma (Firehose Legacy, n = 606).
