Additionally, several SNPs linked to both COVID-19 severity and CHD have been found in several genes, including leucine zipper transcription factor-like 1 (LZTFL1), histo-blood group ABO system transferase (ABO), inflammation and lipid regulator with UBA-like and NBR1-like domains (ILRUN), and calcium channel flower domain containing 1 (CACFD1) [145]. Here, ILRUN is linked to coronary artery disorder.
