Our little man has been found to have some genetic abnormalities with number 15 Chromosome. His symptoms include developmental delays, severe speech delay, hypotonia, different facial features...the list goes on. There has been no formal diagnosis yet, as we have to see a Genetic Counsellor following our next paediatrican appointment but after reading some stuff on the net, we are trying to educate ourselves on what it may be so we are prepared. Angelman's and Prader-Willi syndromes have been ruled out although he has some of these symptoms, but we discovered another very rare syndrome called 15g4 microdeletion syndrome on an American genetic website today...so can't wait to find out more. Whatever he has it won't change our course of action for him at this stage...so on with the physio and speech therapy. Anyone out there had any similiar experiences?
