Furthermore, an inverse association for genetically proxied concentrations of Beta-Chemokine RANTES (RANTES/CCL5) in relation to serous ovarian cancer (0.70, 0.57 to 0.85, p = 3.8 × 10−4) was found, which was based on a single instrumental variable, hence no sensitivity analyses were performed. The gene discussed is CCL5; the disease is ovarian serous adenocarcinoma.
