My oldest child has the same abnormal DNA as my DH, and I am tested normal. The genetic testing result is not really helpful or linked to any diagnosis but at least he contributes to the medical research study with his additional case. Well, he has asd, adhd, epilepsy and global apraxia. DH has adhd and asd. My youngest child has asd, adhd and learning delays. All of my kids and DH are high functioning, and they are expected to live independently. Should I test my youngest child on genetic testing as well? We cannot figure out why my youngest has learning delay.
