The Human Phenotype Ontology (HPO) provides the following list of features that have been reported in people with this condition. Much of the information in the HPO comes from Orphanet, a European rare disease database. If available, the list includes a rough estimate of how common a feature is (its frequency). Frequencies are based on a specific study and may not be representative of all studies. You can use the MedlinePlus Medical Dictionary for definitions of the terms below.
| Signs and Symptoms | Approximate number of patients (when available) |
| Thrombocytopenia | Very frequent (present in 80%-99% of cases) |
| Thromboembolism | Very frequent (present in 80%-99% of cases) |
| Arterial thrombosis | Frequent (present in 30%-79% of cases) |
| Petechiae | Frequent (present in 30%-79% of cases) |
| Purpura | Frequent (present in 30%-79% of cases) |
| Bruising |
Occasional (present in 5%-29% of cases) |
| Epistaxis | Occasional (present in 5%-29% of cases) |
| Gastrointestinal hemorrhage | Occasional (present in 5%-29% of cases) |
| Gingival bleeding | Occasional (present in 5%-29% of cases) |
| Cerebral hemorrhage | Very rare (present in 1%-4% of cases) |
| Abnormal bleeding | - |

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.
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.

Autoinflammation 2013: The Seventh International Congress of FMF and Autoinflammatory Diseases Wednesday, May 22, 2013 -
Sunday, May 26, 2013
Location:
Lausanne,
Switzerland
Description: The goals of this meeting include the exchange of clinical and scientific information regarding the autoinflammatory diseases. This is likely to result in improvements in the diagnosis and treatment of these diseases. Past Congresses have resulted in new scientific collaborations, development of registries for patients with specific autoinflammatory disorders, and the initiation of multicenter clinical trials.

Is idiopathic thrombocytopenic purpura hereditary? See answer
I was first diagnosed with idiopathic thrombocytopenic purpura, which then progressed to Evans syndrome. I had a splenectomy and have since been in remission. My husband and I have been together for 10 years, and in this time I have not conceived. Can Evans syndrome cause infertility? If I do get pregnant, would there be a chance my child could have the same condition? See answer
Can lupus, antiphospholipid syndrome, and ITP antibodies occur together? How is this treated? See answer
