IFNG and schistosomiasis: The observation made here that STAT6 rs324015 was associated with elevated schistosome egg antigen-specific IFNγ may have implications for early immune responses such as reducing TH2-mediated immunopathology following egg deposition, and examination of the immunological consequences of this SNP and others on responses to schistosomiasis would shed further light on the role of host genetics in S. haematobium infection.
