First, cases of autoimmune hemolytic anemia have been linked to SARS‐CoV‐2 infection (Lazarian et al., 2020) a phenomenon that has been attributed to the high molecular similarity between the SARS‐CoV‐2 spike protein and the protein ankyrin 1 found on RBC surfaces (Angileri et al., 2020)In COVID‐19 patients who develop a severe or critical illness, intravascular coagulopathy, either localized to the lung parenchyma or disseminated, is also common (Lippi et al., 2020). The gene discussed is ANK1; the disease is blood coagulation disease.
