Research helps us better understand diseases and can lead to advances in diagnosis and treatment. This section provides resources to help you learn about medical research and ways to get involved.
Support and advocacy groups can help you connect with other patients and families, and they can provide valuable services. Many develop patient-centered information and are the driving force behind research for better treatments and possible cures. They can direct you to research, resources, and services. Many organizations also have experts who serve as medical advisors or provide lists of doctors/clinics. Visit the group’s website or contact them to learn about the services they offer. Inclusion on this list is not an endorsement by GARD.
These resources provide more information about this condition or associated symptoms. The in-depth resources contain medical and scientific language that may be hard to understand. You may want to review these resources with a medical professional.

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
