Autosomal dominant

Includes all the Type 1 CMT’s and most of the Type 2’s

Here the condition becomes apparent even though the affected person has only one abnormal gene. Either sex can have the condition and each child of an affected parent has a 50% chance of being affected.

However, the severity of the condition may vary considerably in different individuals. Some people are so mildly affected that they may not have recognised that they have the condition but they may then have a more severely affected child. So examination of all the family members is important as part of genetic counselling.
