A study identified nine ferroptosis-related genes with prognostic value in breast cancer: BCL2, SUSD3, SERPINA3, AGBL2, SEC14L2, ELOVL2, FGD3, CASC1, and TPRG1. The prognostic model based on these genes showed that patients with high ferroptosis scores had significantly better overall survival (OS) than those with low ferroptosis scores. The gene discussed is SUSD3; the disease is breast cancer.
