MBL2 and viral infectious disease: Preliminary analysis of a small cohort of RRV patients does not associate Mbl2 polymorphisms with severity of RRV disease (S. Mahalingam, B. Piraino, B. Cameron, L. Herrero, and A. Lloyd, unpublished data), however a larger cohort of RRV-infected individuals must be analyzed before we can conclude whether MBL polymorphisms associate with RRV-induced disease severity or if up-regulation of MBL in response to viral infection contributes to disease pathogenesis in humans.
