Poliovirus infections can be asymptomatic or cause severe paralysis. Why some individuals develop paralytic poliomyelitis is unknown, but a role for host genetic factors has been suggested. To investigate if a polymorphism, Ala67Thr, in the poliovirus receptor, which has been found to facilitate increased resistance against poliovirus-induced cell lysis and apoptosis, is associated with increased risk of paralytic poliomyelitis, poliovirus receptor genotyping was undertaken among Italian subjects with vaccine-associated (n = 9), or with wild-type paralytic poliomyelitis (n = 6), and control subjects (n = 71), using RFLP-PCR and pyrosequencing. Heterozygous poliovirus receptor Ala67Thr genotype was found in 13.3% of the patients with paresis and in 8.5% of the controls (Odds Ratio = 1.667). The frequency of Ala67Thr among the controls is in agreement with earlier published data. It is concluded that the Ala67Thr mutation in the poliovirus receptor is a possible risk factor for the development of vaccine-associated or paralytic poliomyelitis associated with wild-type virus.
