IFNG and subacute sclerosing panencephalitis: 2014). Another study uncovers that having the AA genotype or A allele decreases the risk of SSPE, as most healthy individuals expressed this genotype (Figure 2). The AA genotype at the −1188 position decreases the risk of developing SSPE by 2.1‐fold, while the A allele reduces it by 1.6‐fold. However, in this study, there was uncertainty in the IFNG polymorphism as no correlation was appreciated with SSPE patients (Dundar et al. 2016).
