For instance, association of C1qB gene polymorphism with schizophrenia was demonstrated in an Armenian population and it was suggested that the“C1qB gene may be considered as a relevant candidate for susceptibility to schizophrenia.” Interestingly, Severance et al. suggested the hypothesis that food antigens could be the source of activation of the complement system, and that these antigens could bind and activate the C1q, the first component in classical activation of the complement system. Here, C1QB is linked to schizophrenia.
