Kaplan-Meier plotter analysis showed that the prognosis of FMNL2 was only statistically significant in ER-negative subtyping of breast cancer, and the low FMNL2 expression was significantly associated with poor recurrence-free survival (RFS) probability in ER-negative and basal subtyping of breast cancer (Fig. 5B, C). Here, FMNL2 is linked to breast carcinoma.
