Hi my daughter is nearlly 11months old.. She has smith magenis syndrome at the moment they are investigating fluid on her left ventricle. Its measuring nearlly 2cm it hasnt stopped growing since birth and its only because ive been so rude about it that they are investigating it.. Whats the dangerous level for her age? She is very irritable all the time but i can never tell if they are s symptoms of the brain or of the syndrome..
Hello, Smith Agents syn Chat Doctor.  Among the physical effects, it can cause heart defects. There are also behavioral and emotional effects such as irritability.  I am sorry, but I do not know what "fluid on the ventricle" is. It is VITAL that she be EVALUATED and FOLLOWED by a behavioral-developmental pediatrician(these specialists are found at a University Medical School in the Department of Pediatrics).  This type of physician can describe to you(and your spouse and others who are involved with her care) features of SMS and how her behaviors are likely to be as she grows. Here is how to contact an organization of parents and others who are involved with SMS: www.prisms.org.  Another source of information is Genetic & Rare Disease Information Center(associated with NIH) whose telephone number: 1-888-205-2311. Hope I have answered your query. Let me know if I can assist you further. Take care
