title: The molecular genetics of inflammatory, autoimmune, and infectious diseases of the sinonasal tract: a review.
abstract: BACKGROUND
  The sinonasal tract is frequently affected by a variety of nonneoplastic inflammatory disease processes that are often multifactorial in their etiology but commonly have a molecular genetic component.
  
  
  OBJECTIVE
  To review the molecular genetics of a variety of nonneoplastic inflammatory diseases of the sinonasal tract.
  
  
  METHODS
  Inflammatory lesions of the sinonasal tract can be divided into 3 main categories: (1) chronic rhinosinusitis, (2) infectious diseases, and (3) autoimmune diseases/vasculitides. The molecular diagnosis and pathways of a variety of these inflammatory lesions are currently being elucidated and will shed light on disease pathogenesis and treatment.
  
  
  CONCLUSIONS
  The sinonasal tract is frequently affected by inflammatory lesions that arise through complex interactions of environmental, infectious, and genetic factors. Because these lesions are all inflammatory in nature, the molecular pathology surrounding them is most commonly due to upregulation and down-regulation of genes that affect inflammatory responses and immune regulation.
