TLR3 and cytomegalovirus infection: As observed in Table 2, carriers of the minor TLR3 allele in the homozygous state (TT) had a lower 12-month incidence of CMV infection (40.0%) compared than homozygotes (CC) or heterozygotes (CT) for the reference allele (51.0% and 66.2%, respectively) (P-value = 0.036).
