7% vs 5.5%, OR (95% CI) = 36 (26.55-48.81), P less then 0.0001]. HLA-B allelic variation did not associate with seropositivity for anti-VCA IgA in either group. Results from this study show, more clearly than previously, the existence of a cluster of low-frequency and rare HLA-B variants conferring low, or very low risk to NPC, a phenomenon not observed in other ethnic groups. Our data shed new insights into genetic susceptibility to NPC in southern Chinese populations. Future independent studies are warranted to replicat
