This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

You can find laboratories offering clinical and research genetic testing for ALS through the Genetic Testing Registry (GTR). The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional.

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.
Living with a genetic or rare disease can impact the daily lives of patients and families. These resources can help families navigate various aspects of living with a rare disease.

What are the chances of passing on sporadic ALS to offspring? Are there cases where a sporadic case became the first of an autosomal dominant inheritance? See answer
Does a father who develops ALS in his late forties have an increased risk for his son or future generations to have ALS? See answer
Is there any proof that a special diet helps slow down the progression of ALS? Are there any impending cures? Is it true that riluzole is most effective for patients with bulbar-onset? See answer
