I was just diagnosed with charcot marie tooth at 40 years old. Is it common to be diagnosed at this age? When should I have my children tested?

Symptoms ??? Genetic counseling and testing is advised if there is a strong family history of the disorder. Call for an appointment with your health care provider if there is persistent weakness or decreased sensation in the feet or legs. http://www.cmtausa.org/index.php?option=com_content&view=article&id=74.
Charcot-Marie-Tooth . Charcot-marie-tooth disease is of variable inheritance and causes muscular atrophy. You should consult your physician and a geneticist.
ASAP. As CMT is an inherited condition, the sooner you are tested the better. Since the syndrome has so many variable manifestations, and early intervention helps ensure appropriate medical treatment, it is wise to have genetic testing and counseling as soon as possible.
