The proteins identified by artificial intelligence with the highest predictive values for COVID-19 disease severity were the following: CRK-like proto-oncogene, adaptor protein (CRKL), interleukin 1 receptor-associated kinase 1 (IRAK1), NF-kappa-B essential modulator/inhibitor of nuclear factor kappa-B kinase subunit gamma (NEMO/IKBKG), axis inhibition protein 1 (AXIN1), serine/arginine-rich protein-specific kinase 2 (SRPK2), and the cytoplasmic histidine–TRNA ligase (HARS1) [10]. Here, SRPK2 is linked to COVID-19.
