The Human Phenotype Ontology (HPO) provides the following list of features that have been reported in people with this condition. Much of the information in the HPO comes from Orphanet, a European rare disease database. If available, the list includes a rough estimate of how common a feature is (its frequency). Frequencies are based on a specific study and may not be representative of all studies. You can use the MedlinePlus Medical Dictionary for definitions of the terms below.
|Signs and Symptoms||Approximate number of patients (when available)|
|Corticospinal tract atrophy||-|
|Proximal muscle weakness||-|
|Retinal pigment epithelial mottling||-|

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.
Nonprofit support and advocacy groups bring together patients, families, medical professionals, and researchers. These groups often raise awareness, provide support, and develop patient-centered information. Many are the driving force behind research for better treatments and possible cures. They can direct people to research, resources, and services. Many groups also have experts who serve as medical advisors. Visit their website or contact them to learn about the services they offer. Inclusion on this list is not an endorsement by GARD.

2011 Neurobiology of Disease in Children Symposium: Childhood Ataxia
Tuesday, October 25, 2011
Location: Savannah, GA
Description: The overall aims of this NDC symposia are to (1) review scientific advances and determine their relevance to current and future clinical practice in child neurology; (2) coordinate efforts among various clinical and basic science disciplines, lay organizations, and the NIH to review current research initiatives and define future directions; and (3) disseminate symposia proceedings to ensure that clinical and basic science disciplines are informed about scientific advances, current research initiatives, and future directions. NDC symposia have brought together clinicians, scientists, caregivers, and NIH program officers to determine how research findings can be translated to enhance clinical understanding and affect clinical practice.
