In addition, the rs7851696 variant in the FCN2 gene has been associated with delayed graft function and acute graft rejection in renal transplant patients (T allele = OR 1.71; 95% CI: 1.02-2.87, p value = 0.048) [22]; in other diseases such as vasculitis, ficolin-M expression is elevated in peripheral blood mononuclear cells and inflamed areas [23] and severe pneumonia in the Egyptian population [24]. This evidence concerns the gene FCN1 and pneumonia.
