I am Nagarasan in India. I am affected with congental myotonia from childhood. What genetic counseling is there for curing this in gene theraphy.

Gene therapy is still not an approved therapy in human beings.

However, limited symptomatic treatment may be available.

Also, if you have the genetic confirmation of the disorder, you can potentially prevent the future generation from inheriting the same condition.
