I have been diagnosed with HSAN type 1. My daughter is showing probable signs of the same. I have 2 sons that are not showing these same signs. Is it possible for my sons to be carriers of this condition and pass the mutation on to their children? Are there any resources for good information on this disease? I will do everything possible to help my children and grandchildren understand this condition. My doctor does not feel genetic testing is necessary due to the huge expense and great possibility of having a false negative outcome. Should I continue with this in your opinion? See answer
