Interestingly, ADNP inducing antibodies to influenza, FcγR3A-NK cell activating antibodies to tetanus and Varicella zoster virus, FcRn binding antibodies to adenovirus T40 and norovirus, and overall levels of S. pneumoniae antibodies were preferentially lost over the first week of life (Fig. 7C). The gene discussed is FCGR3A; the disease is influenza.
