evidence: Do variants of the MTHFR gene cause disease and increase the likelihood of vaccine reactions? No, that's not true: In rare circumstances, a MTHFR (methylenetetrahydrofolate reductase) gene variant causes neural tube defects in newborn babies. Other times, it can cause elevelated levels of homocysteine, which can lead to blood clots. Otherwise, there are no scientific studies linking MTHFR gene variants, often called mutations, to any diseases or vaccine reaction. And certainly no relation has been found to the skin conditions shown in the photos, which are relatively common and benign. [...] These are indicators of the MTHFR gene.The MTHFR gene is involved in a process called "methylation." Methylation determines how genes are expressed, how enzymes function, and how your body clears toxins. Our body needs to be able to detox properly with the amount of toxins we come in contact everyday.If this "methylation system" isn't working right ... you could experience depression, fibromyalgia, migraines, autism, birth defects, low energy, infertility, elevated levels of homocysteine, gotta sleep right now fatigue, IBS, ADD/ADHD, migraines, thyroid disfunction, metabolism disorders, autoimmune diseases, and even cancer...When people have MTHFR their chances of vaccine reactions increase because they cannot detox the toxins from the vaccines. [...] Nor are there any studies substantiating any connections between MTHFR gene variants and adverse health effects in relation to vaccinations. Here's what we know:
