Polymorphisms of IFN-γ T/A +874 Gene and Relationship with COVID 19 in Iraqi Population

Abstract This study included 80 blood specimens. Fifty samples collected from COVID 19 with age ranged between 02-75 years, and 30 specimens healthy as a control sample 91-63 years. The polymorphism of IFN-γ T/A +874 gene, which amplified by using amplification refractory mutation system (ARMS-PCR) was showed high percentage A allele frequency in patients comparison T frequency, the revealed etiological fraction risk having disease, whereas specimen, preventive infection this disease. AA TA genotypes TT genotype Our findings demonstrate that Gene gene may represent significant factor for Iraqi population there is association patients.
