IFNG and susceptibility to pneumonia measurement: Using PCR-DNA sequence verdicts, the IL-1α (356-bp), IL-1β (423-bp), IL-6 (384-bp), TNFα (490-bp), IL-10 (306-bp), IFN-γ (321-bp), PRDX6 (434-bp), ATG7 (416-bp), NDUFS6 (405-bp), and NOX4 (396-bp) genes were found to have different SNPs in the amplified DNA bases linked to pneumonia.
