15q11.2 Micro Deletion!

My Youngest son G, recently had genetic testing done. The results came back that he has 15q11.2 Microdeletion. This is a tiny part of the 15th chromosome. So here is a run down. When an embryo is formed the sperm and egg come together each with their half of the 24 chromosome's to make 24 pairs of chromosomes. Sometimes this is not the case. There are many many variations to the genetic sequence that can cause an abundant amount of problems. The deletion G has is part of the 15th chromosome. The 11.2 part to be exact. G's deletion is part of the gene that cause's Angleman syndrome. This deletion is so rare that the only information they have, is a compiled list of the 50 our so people documented with the deletion. It reads something like this 8 year old male, ADHD. 12 year old female mental ability of A 4 year old. The list goes on and on like that in a horribly frustrating way. When you google 15q11.2 micro deletion the words schizophrenia, autism, ADHD, OCD, pop up, all of this just opens new doors, and doesn't answer any of the questions we had that led to the testing to begin with. I as a mother am totally lost, and do not know what to do next.
