There was a small study of patients with hypertension (high blood pressure) who belong to a genotype found in 10% of the world population- many of whom are from Northern China (20%) and Mexico (32%). In a small but well done study their blood pressures were reduced with a small dose of Vitamin B2 (Riboflavin). The drop could be enough on its own, but it could bring blood pressures into the normal range with medications where before it was difficult to get enough control. First, it may be worth discussing this with your health care provider. If you are having trouble controlling your blood pressure with medications, there are MANY possible reasons, but a trial of B2 (remember small dose or through your diet) is not unreasonable to see if it helps.
Remember, you truly have little or no idea what your actual gene pool is.
This brings up another topic. I recommend Genetic Geneology. How did we end up where we are today? Where did you really come from? DNA studies have shown that people shared a common ancestor who lived in Africa between 50,000 to 200,000 years ago. As our ancestors migrated out of Africa into the rest of the world, small changes called mutations occurred in their DNA. As generations passed, each mutation links our ancestor to a specific time and place in history. The mutations that we find in our own DNA tell the story of our own ancestral past.
