Is TNF-α gene polymorphism related to pulmonary functions and prognosis as determined by FEV1, BMI, COPD exacerbation and hospitalization in patients with smoking-related COPD in a Turkish population?

Abstract: Introduction: Some conflicting results have been published about the relationship between TNF-␣-308 gene polymorphism and chronic obstructive pulmonary disease (COPD). The aim of this study was to determine whether TNF-␣-308 gene polymorphism was associated with smokingrelated COPD and whether it was associated with pulmonary function parameters (PFTs), body mass index (BMI), and prognosis. Methods: We studied the frequencies of TNF-␣-308 gene polymorphism in 90 male subjects (60 subjects with COPD and 30 heal… Show more

“…In a Japanese population, it has been described that group component (GC) (a protein that binds to vitamin D and affects its concentration) polymorphisms are associated with frequent exacerbations, as well as COPD presence and a tendency for fast pulmonary function decline 48 . Additionally, other genes have been evaluated in different populations, such as SFTPB (Surfactant B protein), MBL (mannose-binding lectin) TNF and SIGLEC9 (Sialic acid-binding Ig-like lectin 9), which were associated with frequent exacerbations [49][50][51][52] . Our results of the unadjusted analysis show a tendency, whereby we believe that if we increase the sample size, we could find an association with rs2275913; therefore, we do not rule out that IL17A polymorphisms are associated with frequent exacerbations.…”
