To determine if downregulation of SLC7A2 in ovarian cancer tissues were caused by genetic variations, we assessed genetic variations of SLC7A2 in the cBio-Portal database which contained information on 1680 ovarian cancer cases from three studies (TCGA, Nature 2011; TCGA, PanCancer Atlas; TCGA, Provisional). This evidence concerns the gene SLC7A2 and ovarian carcinoma.
