Abstract

Abstract: AIM: To investigate and analyze the distribution characteristic of 5,10-methylenetetrahydrofolate reductase (MTHFR) C677T gene polymorphism among cerebral stroke patients and to provide prevention and treatment for stroke patients in southern Anhui Province. METHODS: A total of 114 patients with cerebral stroke in the Second Affiliated Hospital of Wannan Medical College from January 2018 to October 2019 were included. The MTHFR C677T genotype was performed by fluorescence in situ hybridization analysis. The MTHFR C677T gene polymorphism distribution data of the cerebral stroke population in southern Anhui Province was compared with the reported gene distribution data of Han Chinese stroke population in other parts of China. RESULTS:The frequencies distribution of TT, CT and CC genotypes of MTHFR C677T were 28.90%, 50.00%, 21.10%. The frequencies of C and T alleles were 53.95% and 46.05%. There was no gender difference in the distribution of this gene. There were significant difference in CC genotype between Chongqing area, Heilongjiang area and Guangzhou area (P<0.05). There were significant difference in TT genotype between Chongqing area, northern Henan area and Heilongjiang area (P<0.05). CONCLUSION: The distribution of MTHFR C677T gene polymorphism in the Han population of southern Anhui Province is different from other areas. It can provide a scientific basis for the prevention and treatment of cerebral stroke in high-risk population in southern Anhui Province by genetic testing technology.
