Different infection microflora and environment have great influence on the occurrence, development and prognosis of sepsis, but individual genetic factors also play an extremely important role. It was reported that the polymorphisms of mannose-binding lectin 2 gene were closely relevant to the occurrence and development of sepsis, but the conclusions in different studies were inconsistent. Therefore, we performed this reviews on the relevance of mannose-binding lectin 2 gene polymorphisms and sepsis.展开更多
