Abstract

Background: Vitamin D receptor gene (VDR) polymorphism and its association with various diseases have been previously investigated. But the association of vitamin D receptor gene polymorphism with COPD has not been investigated yet.

Objective: To assess the association between vitamin D receptor gene polymorphism (TaqI) and COPD.

Methods: This cross-sectional study was carried out in the Department of Physiology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, from March 2019 to February 2020. For this study, 15 (fifteen) pulmonologists diagnosed COPD patients with age 40 to 80 years (post-bronchodilator FEV1/FVC <0.70 and FEV1 <80% predicted) and 15 (fifteen) apparently healthy age-matched individuals (for comparison), were selected. The single nucleotide polymorphism of the vitamin D receptor gene (TaqI) of all subjects was assessed by PCR-RFLPs. Data were expressed as mean ± SD and percentage. Statistical analysis was done by independent sample‘t’ test and chi-square test. In the interpretation of the results, ≤ 0.05 level of probability (p) was accepted as significant.

Results: The frequency distribution of the TaqI VDR SNP was 0% (TT), 0% (Tt), 100% (tt) and 0% (TT), 0% (Tt), 100% (tt) COPD patients and healthy subjects, respectively. There was no association between TaqI VDR SNP with COPD.

Conclusion: The present study reveals that TaqI of VDR SNP is not associated with COPD.
