Hello Doctor, My three year old daughter has a BSD, has distonia leg muscle issues on both legs, and just recently I ve noted age spots-- a lot of them across the trunk of her body, and her very blonde hair seems to be turning grey. I have an appointment in a couple of weeks with a genetics specialist, but I ve very worried, and would like to know anything you can help them figure out what s wrong with my daughter. Please give me any info you can on what tests I can ask for etc. --Very worried Mom.
