The tumor necrosis factor α (-308 A/G) polymorphism is associated with cystic fibrosis in Mexican patients.
<h4>Unlabelled</h4>Environmental and genetic factors may modify or contribute to the phenotypic differences observed in multigenic and monogenic diseases, such as cystic fibrosis (CF). An analysis of modifier genes can be helpful for estimating patient prognosis and directing preventive...
