The results indicated that six genes exhibited a high predictive accuracy for the development of HF after AMI, including B-cell leukemia/lymphoma 3 (BCL3), hematopoietic cell kinase (HCK), peptidylprolyl isomerase F (PPIF), S100 calcium binding protein A9 (S100A9), serpin family A member 1 (SERPINA1), and TBC1 domain family member 9B (TBC1D9B). The gene discussed is TBC1D9B; the disease is hydrops fetalis.
