We obtained the risk prediction model for BC through LASSO regression analysis and identified seven marker regulators in different survival periods for BC patients, in which KIAA1429, WYAP, and ZC3H13 were classified as ‘writer’, FTO was classified as ‘eraser’, and HNRNPC, YTHDC2, and YTHDF1 were classified as ‘reader’ in relationship to their m6A modifications. Here, HNRNPC is linked to breast cancer.
