We found that CEP55 mRNA expression is associated with the PAM50 breast cancer molecular subtypes (Luminal A, Luminal B, HER2, and basal‐like), with the basal‐like subtype exhibiting significantly higher expression of CEP55 compared to other subtypes (P < 0.0001; Fig EV1A, available online). The gene discussed is CEP55; the disease is breast cancer.
