NR2F1 and breast neoplasm: There was no difference in mutation rates by the level of NR2F1 expression in a bulk tumor, however; immune-related scores such as IFN-γ response and TIL fractionation, as well as immune cell infiltrations such as Th1 and Th2 T cells and M1 and M2 macrophages, were all less in NR2F1 high expression breast tumors.
