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.

My 22 year old son was diagnosed with urticaria pigmentosa in infancy and except for skin spots he is largely symptom-free. Because of increasing skin spots and elevated serum tryptase, he had bone marrow tests and was diagnosed with indolent systemic mastocytosis (ISM). He does not have other health problems and is very active. Will his symptoms worsen systemically with time or is it possible for ISM patients to remain symptom-free for life? See answer
My mother is suffering from systemic mastocytosis. What types of treatment are available for this condition? See answer
I need information on the initial tests that can be done to rule out systemic mastocytosis. What are they and should they be done after an episode or can they be done at any time? See answer
Can heat and/or humidity affect systemic mastocytosis? See answer
