Your QuestionMy daughter's father was diagnosed with CMT1A in childhood. My daughter is very active and we decided to not have her tested, unless she shows symptoms. I have noticed that her hands sometimes shake. Should this be a concern? Also she walks on her tip toes. She has since she started walking. However I did too as a child and I don't have the disease. Her father has stated that he has never been physically able to walk on his toes even as a child. I read so many things on the internet and it's so confusing. Her feet do not look abnormal. Anyway I was just wondering about the toe walking and the hands shaking sometimes.

Toe walking is not typically an early sign of CMT1A, rather more often it is a "slap foot gait" due to weakness in the lower legs (foot drop). Clumbsiness or frequent tripping are other early signs. As CMT1A progresses a person may develop tight heel cords. Children with tight heel cords often walk on their toes, however toe walking is a common habit among unaffected children as well.
