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.

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.
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.

Gordon Research Conference and Gordon Research Seminar on Lysosomes and Endocytosis
Sunday, June 15, 2014 -
Friday, June 20, 2014
Location: Proctor Academy, Andover, NH
Description: The main goal of the Lysosomes and Endocytosis GRC is to foster the dissemination of current research results and the establishment of new research areas and new collaborations in the area of the cell biology of endocytosis, lysosomes, endosomes and related organelles. We hope that many of these new directions and collaborations will be directed toward the etiology, diagnosis and treatment of rare genetic diseases such as lysosomal storage disorders, Hermansky-Pudlak syndrome, Chediak-Higashi syndrome, Niemann Pick disease and tuberous sclerosis, among others.

My daughter was diagnosed with MPS 3A. How is this condition managed and are there possibilities of a cure? See answer
My family is known to carry the genes for Sanfilippo A or MPS IIIA. Is there a test that I can request when I conceive to know if my child will have the disease? I understand to have myself/my husband tested it is very pricey. What options do we have? How early can we test a fetus? My cousin had the disease and any help would be greatly appreciated. See answer
