                         My son, 12, was has not yet been diagnosed. But he has symptons like those discribed xyy syndrome: very active and problems at school - similar to klinefelters but  fysically normal.  If you would like to korrespond with me a litte, could you tell me, if having a diagnosis makes a differens?
