Abstract
BACKGROUND

Variations in the methylene tetrahydrofolate reductase (MTHFR) gene have been reported as risk factors for numerous conditions, including cardiovascular disease, thrombophilia, stroke, hypertension and pregnancy-related complications. Moreover, it was reported there is an association between breast cancer and mutations in MTHFR-C677T. However, whether there is an association between MTHFR gene polymorphism and granulomatous lobular mastitis or not has been rarely investigated.

AIM

To analyze the association between MTHFR gene polymorphism and granulomatous lobular mastitis.

METHODS

Fifty-one patients with granulomatous lobular mastitis admitted to The First Hospital of Kunming were selected as study samples. Their hospitalization time ranged from February 2018 to February 2019. The 51 patients were included in the experimental group, and another 51 women who underwent physical examination at The First Hospital of Kunming in the same period were included in the control group. Deoxyribonucleic acid and MTFR genetic polymorphism testing were performed in each group. The association between MTHFR gene polymorphism and granulomatous lobular mastitis was observed.

RESULTS

There were significant differences in genotype frequency and allele frequency of C/C and C/T between the experimental group and the control group (all P < 0.05). However, there was no significant difference in frequency of T/T genotype between the two groups (P > 0.05). In addition, there was no significant difference in genotype frequency and allele frequency of A/A, A/C and C/C between the two groups (P > 0.05).

CONCLUSION

MTHFR gene C677T locus polymorphism is closely related to granulomatous lobular mastitis.

Core Tip: Methylene tetrahydrofolate reductase (MTHFR) gene polymorphism is associated with several diseases. It was reported that mutations in MTHFR-C677T is associated with breast cancer. We tested the association between MTHFR gene polymorphism and granulomatous lobular mastitis in patients with this disease. The results supported our hypothesis that MTHFR C677T is a susceptibility factor that may influence the occurrence of granulomatous lobular mastitis.
