The genetic data were based on gene pathway analysis in one study [40], whereas the remaining two studies focused on single gene analysis, that is either BRCA mutation status [39] or Classification of Ovarian Cancer transcriptomic (CLOVAR) subtypes (differentiated, immunoreactive, mesenchymal, and proliferative), and amplification of 19q12 involving cyclin E1 gene (CCNE1) [38]. The gene discussed is CCNE1; the disease is ovarian cancer.
