My eight year old son cannot speak or communicate at all, he has daily meltdowns, and cannot stand on his own. He's never crawled or pulled to stand, and loud or sudden noises make him cry. He is missing a piece of DNA (chromosome 9q22.2) but we are unsure if it made him disabled. His MRI gave us a diagnosis of partial agenesis of the corpus callosum and microcephaly. He is severely multiply impaired, has hypotonia and has also been diagnosed with Autism.
