These proteins either act as positive regulators of cell death (HBG1, HBB, HBD, and HBA1) or are involved in the cellular response to tumor necrosis factor (FABP4, GPD1, THBS1, ASS1, and PCK2), suggesting that apoptosis may be an important cause of heart failure in patients with COVID-19. The gene discussed is HBB; the disease is COVID-19.
