I am a carrier of the Fragile x gene. I didn't know this until Kyle was diagnosed...I had never heard of the gene before that time.
Fragile X syndrome is the most common known single gene cause of autism.
Approximately 1 in 260 (maybe ever 1 in 130) women and 1 in 800 men carry this gene.
Fragile X is the most common cause of inherited mental impairment. This impairment can range from learning disabilities to more severe cognitive or intellectual disabilities.
