My son has the full mutation of Fragile X. It is the leading genetic cause of autism. My son is mild, only suffering from learnng disabilities. It is passed through families for generations without being detected. Being a carrier of FX comes with a host of issues. I went through menopause at 25 years of age. I was diagnosed with sciosis when I was twelve and am now getting the surgery on August 1 st. all these health problem are associated with being a carrier of fragile X. There are also a host of other muscular conditions. So I definitely know where my scoliosis came from. My son is 14 and doesn't have scoliosis. I am very thankful.
