Autoimmune lymphoproliferative syndrome (ALPS) is a disorder in which the body cannot properly regulate the number of immune system cells (lymphocytes). This results in the overproduction of lymphocytes, which build up and cause enlargement of the lymph nodes, liver and spleen. Affected individuals have an increased risk of developing cancer of the immune system cells (lymphoma) and may be at increased risk for other cancers. They can also have a variety of autoimmune disorders, most of which damage the blood cells. Some of the autoimmune disorders associated with ALPS can also damage the kidneys, liver, eyes, nerves, or connective tissues. Symptoms may include skin rashes, panniculitis, arthritis, inflammation of blood vessels (vasculitis), mouth sores, premature ovarian failure, and the development of neurological damage. ALPS is caused by genetic changes in the FAS gene in most cases. It is usually inherited in an autosomal dominant manner, although a small number of cases are inherited in an autosomal recessive manner. Some cases are also believed to arise from a genetic change in the lymphocytes that is not inherited, but instead occurs during the course of an individual's lifetime. This type of alteration is called a somatic genetic change.

When Do Symptoms of Autoimmune lymphoproliferative syndrome Begin?
Symptoms of this disease may start to appear at any time in life.
The age symptoms may begin to appear differs between diseases. Symptoms may begin in a single age range, or during several age ranges. The symptoms of some diseases may begin at any age. Knowing when symptoms may have appeared can help medical providers find the correct diagnosis.

Immune System
The immune system is a complex network of cells, tissues, and organs that together help the body fight infections and other diseases. This system is made up of the skin, mucous membranes, white blood cells, and organs and tissues of the lymph system, including the thymus, spleen, tonsils, lymph nodes, lymph vessels and bone marrow. Common symptoms of problems in the immune system include fatigue, joint pain, skin rash, abdominal pain or digestive issues, fever, swollen glands, repeated infections, or headaches. Diseases of the immune system may be diagnosed and treated by an allergist, immunologist, or rheumatologist.

Description
The occurrence of an immune reaction against the organism's own cells or tissues.
Autoimmune lymphoproliferative syndrome is caused by genetic mutations, also known as pathogenic variants. Genetic mutations can be hereditary, when parents pass them down to their children, or they may occur randomly when cells are dividing. Genetic mutations may also result from contracted viruses, environmental factors, such as UV radiation from sunlight exposure, or a combination of any of these. Learn more about genetic diseases from the National Library of Medicine (NLM).
If you suspect you may have this disease, you may want to start collecting your family health history. Information such as other family members who have had similar symptoms, when their/your symptoms first appeared, or exposures to any potential disease-causing environmental factors should be discussed with your medical team. This tool from the Surgeon General can help you collect your family health history.
Can This Disease Be Passed Down From Parent to Child?
Yes. It is possible for a biological parent to pass down genetic mutations that cause or increase the chances of getting this disease to their child. This is known as inheritance. Knowing whether other family members have previously had this disease, also known as family health history, can be very important information for your medical team. This tool from the Surgeon General can help you collect your family health history.
There are multiple ways, or patterns, a disease can be inherited depending on the gene(s) involved. Based on GARD's current data, this disease can be inherited in the following pattern(s):
Autosomal Dominant
Autosomal means the gene involved is located on one of the numbered chromosomes. Dominant means that a child only needs to inherit one copy of the mutated gene, from either biological parent, to be affected by the disease.
People affected by an autosomal dominant disease have a 50% chance of passing on the mutated gene to their biological child.
Patient organizations can help patients and families connect. They build public awareness of the disease and are a driving force behind research to improve patients' lives. They may offer online and in-person resources to help people live well with their disease. Many collaborate with medical experts and researchers.
Services of patient organizations differ, but may include:
Ways to connect to others and share personal stories
Easy-to-read information
Up-to-date treatment and research information
Patient registries
Lists of specialists or specialty centers
Financial aid and travel resources

Clinical studies are part of clinical research and play an important role in medical advances, including for rare diseases. Through clinical studies, researchers may ultimately uncover better ways to treat, prevent, diagnose, and understand human diseases.
What Are Clinical Studies?
Clinical studies are medical research involving people as participants. There are two main types of clinical studies:
Clinical trials determine if a new test or treatment for a disease is effective and safe by comparing groups receiving different tests/treatments.
Observational studies involve recording changes over time among a specific group of people in their natural settings.
People participate in clinical trials for many reasons. People with a disease may participate to receive the newest possible treatment and additional care from clinical study staff as well as to help others living with the same or similar disease. Healthy volunteers may participate to help others and to contribute to moving science forward.
To find the right clinical study we recommend you consult your doctors, other trusted medical professionals, and patient organizations. Additionally, you can use ClinicalTrials.gov to search for clinical studies by disease, terms, or location.
What if There Are No Available Clinical Studies?
ResearchMatch helps connect people interested in research studies with researchers from top medical centers across the United States. Anyone from the U.S. can register with this free program funded by NIH. Researchers from participating institutions use the database to search for and invite patients or healthy volunteers who meet their study criteria to participate.
Join the All of Us Research Program!
The All of Us Research Program is inviting 1 million people from all backgrounds across the U.S. to help build one of the most diverse health databases in history. Researchers will use the data to learn how our biology, lifestyle, and environment affect health. This may one day help them find ways to treat and prevent diseases.
