MIF and disease arising from reactivation of latent virus: Our data show that the frequency of the G minor allele of MIF rs36086171 was higher in cases than in controls (uncorrected p = 0.0239, OR = 1.65, CI95 = [1.07–2.53]) and MIF rs12483859 C allele in latent infections than in controls (uncorrected p = 0.0077, OR = 1.86, CI95 = [1.18–2.95]).
