I am finding an alarming increase in 677 and 1298 mthfr mutation in people which I feel because of stress (biological,neurological,lifes tyle, environmental, psychological, structural) genes are being expressed. The result of these gene expression is a potential dramatic increase in neurological, cancer, autism, and other degenerative health disorders. Parents I have found having these mutations are now having their child tested which are also showing up positive. These children who are predisposed with these mutation to mercury vaccines are creating a dangerous scenerio. With the activation of these mutation through gene expression it is not allowing the child to properly detoxify environmental chemicals. The child's altered ability to detoxify is one of the main theories by which autism is on the rise due to the weaken immune system of the child from previous mentioned stressors. I have talked to a number of specialists in the field and they have agree on the same thing. This is the future of America . Its scarey to think about. I have an idea its only going to get worse if we do not take responsiblity for our childrens well being. I also have these mutations and carrier of both, but have taken the necessary steps to protect me from its potential health risks. People will have different views, but like many on the forums are now starting to take it more seriously if they want to get better and also protect their children. One case I just worked on was a 26 year old women who had several miscarriages. The Dr played it off with stress. I decided to look deeper, and what was found was she had both mutations. She was literally in tears when this information was found out. She presented it to her OBGYN who know of it, but said it was rare occurence. Since this was brought to her attention and her doing further research she is now testing ever female patient who is thinking about getting pregnant. I know also recommend any male or female who has a history of neurological, heart disease, stroke to also get tested. Tests are covered by many different insurance if not it can be done for $140 on line..
