Thank you for your query.
I understand your concern.
It is difficult to predict the outcome of your child.But as this is a genetic disorder and a mental problem there is little you can do.
He is going to have a Low IQ.
The aim would be to make himself sufficiently so that he can fend for himself.
and discuss with groups dedicated to learning disorders and autism
The path is difficult but nothing is impossible in this world specially with newer advances in gene therapy
Consult your doctor if the problem aggravates.
If you have any further queries you are free to consult me.
Hope this answers your query.
Wishing a speedy recovery.
Have a nice day.
