I found this discussion searching for answers re: old genetic testing (prior to it officially being considered a “real” concern) revealing that I have two polymorphisms, both C677T and at least one copy of A1298C. If Mayo Clinic recognizes this as affecting health and requiring special nutritional/supplemental intervention, then where must I look for their stance on this condition? How do I schedule an appointment if I can’t find the proper department? I have a huge cluster of health issues and have had since youth including MTHFR related cancer and need current and official genetic testing for insurance and need proper nutritional guidance. My small-town clinic has not been helpful.
