Christopher has 16p11.2 duplication. He has 3 of a part of the p11.2 area on the 16th gene. The doctor said the duplication is better than the duplication and he will fare better. However, he will still have challenges throughout his entire life.
The doctor said that Chris condition isn't anyone's fault. My MIL insists that it's my fault because I couldn't get my prenatal vitamin in. I had hymeramisis! I lost 30 pounds thanks to throwing up. I got a vitamin through the iv's in the hospital. This doctor said that there was a fluke in either my egg or George's sperm that had this condition pre-wired already in it. So when either that particular egg or that particular sperm was used in concieving Chris, he was bound to have this. So, my MIL told me it was my bad eggs with all the things wrong with me. I guess she feels the need to blame someone and I'm the scapegoat.
He has some minor physical characteristics of the syndrome; the gap between his big toe and 2nd toe is bigger than it should and his eye has a slightly larger fold in it than it should. His head is smaller in proportion than his body as well. It is in the 25%.
The deletion has a heart condition associated with it as since Chris has the duplication, we shouldn't worry about it.
The abnormal MRI's he's had done prior to the diagnosis would have been a prime way to diagnosis him as the doctor said that almost ALL children with the duplication and deletion have abnormal MRIs. Chris has something called delayed mylenation. The easiest way to explain it is to think of a computer. Chris' brain is the computer, the neurons etc are the connections the computer needs to run. Chris' connections aren't all the way connected so his brain (computer) will be running slower than it should. Therefore, his capicity to gain new skills is slowed down and this will be a confirmation of intellectual disabilities.
Children with the deletion and duplication have a higher rate of seizure disorders so we need to be mindful of it. He's had 2 seizures when he was less than a year old and the doctor actually suggested what he has been doing that we thought were self stimming behaviors are actually seizure activity. He suggested we follow up with a neurologist for the possible seizure activity and to have periodic MRI's done.
He said that the rate of autism with this disorder is around 80%. Chris has already been diagnosed with PDD_NOS. My mom told me she feels that he was diagnosed as autistic only because WE told the doctors things that aren't true. The doctor who diagnosed him was working with us for a year and a half so he's seen him. The doctor used his observations, what the reports from early intervention say, and what we said to diagnos him. AND, it was confirmed by a doctor who is on the NJ board of directors for the govenor for autism research.
The literature said there's a higher rate of mental illness with this disorder. The doctor said it is only a 10% chance higer than the general population. I'll take my chance that he's on the 90% that don't have, KWIM?
As far as what to expect further down the line...there is not really a way to know what to expect. They said that the technology that was used to find genetic syndromes like this one is only 3 years old and so they haven't done a longitutal study just because the majority of those who have found out about this around around Chris' age. They are doing a study in Boston and NYC that we said we'd be interested in doing.
The doctor also said that Chris NEEDS the PT the school is denying. The syndrome itself has the low muscle tone associated with it and he will forever be clumsy looking, have week core, etc. He sits in a "W" sit and if he goes out of the "W" sitting position he will fall after 10 minutes or so. He also peeters out with eating after about 10-15 minutes. He feeds himself and will get tired from all the work and will get up and we will feed him.
This doctor also said expressive language is more delayed than receptive which is the case for us. Chris is around an 18 month level for expressive but at a 27-30 month level for receptive.
They want us to go back there once a year for followup care, see the neurologist for follow up MRIs, and continue with our other specialists, the ENT, Allergist, eye doctor, developmental ped, etc.
