It has been staring me in the face this whole time! I was diagnosed with heterozygous MTHFR while pregnant with j. This gene mutation can be connected to so many issues I can't even name them all. Specific ones that affect my family are: breast cancer, fibromyalgia, diabetes, arthritis, insulin resistance, fibroid cysts and many more!!! Holy cow!!! Not only this but people with MTHFR can be low on an enzyme that detoxes the body and is linked to autism. Anyway when looking further into this I found this study linking it to increased risk of atopic diseases!!! I can't wait to talk to the doctor about this!!! Interesting read posted below!!!
