Interferon -gamma (IFN-gamma) potential was also evaluated for all 11 epitopes, and we found in category 1 (IFN-gamma vs Non IFN-gamma) 5 out 11 epitopes were showing potential to induce the IFN-gamma response against viral infection and among 5 epitopes our best top two selected epitopes (ILIQGIKTLPILEIA: 1034 HLAs and LILIQGIKTLPILEI: 336 HLAs) were present those having highest HLA coverages. The gene discussed is IFNG; the disease is viral infectious disease.
