Genetic Polymorphism of IFNA1 and IFNAR1 Genes in Covid-19 Iraqi Patients

Coronavirus disease 2019 (Covid-19) is a deadly acute respiratory illness brought on by an infection with coronavirus 2. (SARS-CoV-2).The severity of the syndrome was variant among the individuals ranging between severe and mild. Interferons type 1 are one of the cytokines inactive the viral replication. Genetic variation inrs2850015 for IFNA1 and rs202055606 for IFNAR1 were investigated by high-resolution melting analysis. Results showed that TT genotype and T allele of rs20205560 6polymorphism represented a significant positive odds ratio as risk factor for severity while C allele act as protective factor. The rs2850015 polymor phismrevealed conversionT to G,the GG genotype and G allele represented a significant positive odds ratio as risk factor for severity while the T allele represent protective factorfrom severity. It wasbe concluded that the GG geno type and G allele for rs2850015 and TT genotype and T allelemay be associated with severity of Covid-19
