另外兩個基因是 specifically for the IFNAR2 gene, and another, called TYK2, that 「the products of those genes change a person』s chance of becoming critically ill with covid.
重症患者這些基因,發現有功能缺失突變。deleterious genetic variants in the same genes, may provide a stronger driver towards severe disease.

Genetic mechanisms of critical illness in COVID-19
Lee et al. have recently found heterozygous truncation variant in suppressor of cytokine signaling 1 (SOCS 1) in two unrelated COVID-19 patients with autoimmune cytopenias [61]. Heterozygous SOCS 1 loss of function mutations can lead to enhanced interferon signaling and increased immune cell activation, thereby predisposing to immune thrombocytopenia secondary to COVID-19.
