My daughter had a duplication of the 16th chromosome but they didn't send us more detail yet.
My son had Genetic testing. I found it very helpful for him. We found out he had 16p11.2 Deletion and a mutation 17q2 Chromosome.
I had it done before I knew the price. The price doesnt outweigh any of the results they give you unless you are rich. It took me 4 years to pay off the genetic testing. Good Luck.
We did fragile x testing on my son. It was negative.
Genetic testing and drugs were about the only things our insurance covered. We are doing the Fragile X test but my daughter didn't fit the description I've read.
