* Analyzed 325 blood samples taken from donors between October 2017 and July 2018 using DNA extraction and real-time polymerase chain reaction for genetic variant assessment.
* Found that certain genetic variants (g.1691G > A and g.20210G > A) had low frequencies (4%), while variants for methylenetetrahydrofolate reductase (g.677C > T and g.1298A > C) were more prevalent,
