Further, a series of genes, such as cyclin E1 (CCNE1), cyclin B2 (CCNB2), cytochrome P450 family 3 subfamily A member 5 (CYP3A5), and vascular endothelial growth factor A (VEGFA), have been predicted as target genes for diagnosing ovarian cancer [15]. The gene discussed is VEGFA; the disease is ovarian carcinoma.
