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.

Making a diagnosis for a genetic or rare disease can often be challenging. Healthcare professionals typically look at a person’s medical history, symptoms, physical exam, and laboratory test results in order to make a diagnosis. The following resources provide information relating to diagnosis and testing for this condition. If you have questions about getting a diagnosis, you should contact a healthcare professional.
The resources below provide information about treatment options for this condition. If you have questions about which treatment is right for you, talk to your healthcare 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.
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.

WORLD Symposium 2010 (Lysosomal Disease Network's 6th Annual Research Meeting)
Wednesday, February 10, 2010 -
Friday, February 12, 2010
Location: Miami Hilton Downtown, Miami, Florida
Description: The specific aims of this meeting were to (1) emphasize the strategies for, and identify the obstacles to, moving from translational research to clinical trials; (2) coalesce members of the LD network into functional research collaborations and present to the LDN community progress on the specific projects that are part of the funded U54 RDCRN grant; (3) foster interdisciplinary collaboration with the overall goal of improving knowledge of basic discoveries and clinical manifestations of these diseases; (4) provide an educational forum for young investigators, clinicians, and researchers in the field; (5) identify and discuss the latest findings in the natural history of lysosomal diseases, diagnostic testing and screening, and treatment, with specific focus on (a) inflammatory components of lysosomal diseases and autophagy, especially in the central nervous system, (b) new treatments of the central nervous systems, and (c) ethics and efficacy in treating the presymptomatic or asymptomatic patient; and (6) identify areas requiring additional basic and clinical research and public policy and regulatory attention, such as ethics and economics, and factors that impact implementation of therapy, including newborn screening.
