Prevalence of mutations Methylentetrahydrofolate reductase (MTHFR), Prothrombin (II G20210G/G20210A) and Leyden V factor in patients undergoing studies by thrombophilic profile. Hospital San Vicente de Paul. Costa Rica, 2017 to 2018. PSM [online]. 2021, vol.19, n.1, pp.120-132. ISSN 1659-0201.  http://dx.doi.org/10.15517/psm.v19i2.43749.

Introduction: Genetic alterations associated with a higher or lower risk of thrombotic disease have been reported in recent years, the objective of this study is to understand the prevalence of mutations for methylentetrahydrofolate reductase (MTHFR), Mutation for prothrombin (II G20210G/G20210A) and Mutation for factor V Leyden, in the samples of patients undergoing studies by thrombophilic profile, at the Hospital San Vicente de Paul. Methodology: To carry out this study, we use the database of reference samples of the Hospital San Vicente de Paúl for the study of risk markers for thrombophilia: MTHFR, Ac Lúpico, Mutation of Factor II, Factor V Leyden in the period from April 2017 to April 2018. Results: From the analyses requested for thrombophilia study, the frequency in the thrombophilia study request was observed to be higher for female sex, with a frequency of 83.7% of total testing and 16.3% for the male sex. The most prevalent mutation is MTHFR, followed by the Mutation for factor V Leyden, and both mutations occur in greater numbers in women. Conclusion: The association of genetic alterations studied with thrombotic events has been shown in several studies so knowing their prevalence in a given population is of great importance to help the clinic arrive at an appropriate diagnosis.
