High mRNA expression of OAS2 (HR = 0.34, 95%CI: 0.17–0.67, p = 0.0011) was correlated with better OS in luminal A type cancers (Fig. 2b), whereas OASL was not related to prognosis in luminal A breast cancer (Additional file 1: Figure S1A). The gene discussed is OAS2; the disease is breast carcinoma.
