The Polymorphism of Regulatory Region of NOS3 Gene (rs2070744, Genotype CC) Protect Patients from Chronic Migraine
Journal of Advances in Medicine and Medical Research,
Aims: There is evidence that endothelial nitric oxide synthase has a role in migraine pathophysiology. In our research, the role of SNP rs2070744 (c.-813C>T) in promoter region of NOS3 gene in the episodic and chronic forms of migraine is considered.
Place and Duration of Study: University Headache Clinic between June 2012 and November 2014 and Department of Genetics, Faculty of Biology of Lomonosov Moscow State University between October 2013 and March 2016.
Methodology: The study included 138 patients with migraine (44 with chronic and 96 with episodic migraine). The control group included 348 unexamined subjects. Genotypes were determined using real-time PCR with allelic discrimination test. Statistical processing was performed using Fisher test and Pearson's chi-squared test.
Results: Our study evaluated the link of CC genotype of rs2070744 with migraine (Fisher’s p=0.026) and episodic migraine (Fisher’s p=0.022).
Conclusion: Genotype CC of SNP rs2070744 in the regulatory region of NOS3 gene is more specific for episodic migraine and may prevents the chronification of migraine.
