The frequency of ANGPTL4 immunoreactivity varied among different molecular subtypes of breast carcinoma, higher frequency was observed in the luminal A subtype (n = 19 (38.0%)), followed by triple-negative (n = 14 (28.0%)) and luminal B (n = 9 (18.0%)), while the lowest rate of ANGPTL4 immunoreactivity was observed in the HER2-overexpression subtype (n = 8 (16.0%)). The gene discussed is ERBB2; the disease is breast carcinoma.
