Homeschooler, yes, a full-mutation is a repeat of 200 or more. Our son’s repeats are over 300, but our daughter is only approx. 90. Meaning, she had one “affected X” and one good “X”, so she didn’t show the classic signs. It wasn’t until we had our son (at age 2) tested, and then the family that we discovered my daughter and I were carriers. She’s 20 now and in Honors classes at a local university, and doing great! She’s studying to be a special ed. elementary teacher, and soon to be married. I’m 41 and had on unaffected child, on carrier and one full mutation. My kids range in age from 22, 21 and 4. We were very blessed in discovering this syndrome, because we were sent first to a genetics dr… who just ran a panel of basic blood test, before we would start any other testing. And fragile X came back positive. Our son is 4, but mentally not quite 3 years old. His delay is very obvious, but he looks like any other typical child (he didn’t get the physical markers of Fragile X). He talks some, but not potty trained yet. He has global delays, sensory issues, leg braces for pronated ankles and will begin testing for Autism in Dec. Let me know if you have any more questions… but, I highly recommend a genetic dr. One look at Jonah and he noticed there was something more going on, that just being “slow”. Thanks, Penny
