HMOX1 and COVID-19: A novel SNP (A > G, rs13057211) located within the GT(n) region has recently been identified in COVID-19 patients. This variant was significantly associated with higher mortality (e.g., OR ≈ 3.7, p = 0.021), whereas the length of GT repeats alone did not correlate with survival or HO-1 serum levels (Fares et al., 2023)(Egypt, 90, 90, N/A)
