In systemic mastocytosis, high concentrations may be observed, with greater than 20 ng/mL being a minor criterion for the diagnosis of this condition. For any prenatal specimen that is received, maternal cell contamination studies will be added. 7. This work suggests that multiple alpha tryptase gene copies might underlie health issues that affect a substantial number of people, said NIAID Director Anthony S. Fauci, M.D. While the course of symptoms can be quite variable over time and we do not know the natural history of this disease, we at present have no reason to suspect those with multiple alpha alleles will have a shortened life span.

Measurement of tryptase 1 to 6 hours and at least 24 hours after the anaphylactic episode may be useful in demonstrating a return to baseline concentrations and evaluating the kinetics of the response. In addition to having higher blood tryptase levels, individuals with more alpha tryptase copies also report more shared symptoms.

In the case of hereditary alpha tryptasemia, people with this trait have inherited extra copies of the alpha tryptase gene (TPSAB1), and this leads to increased levels of trypase protein detected in the blood, whether a reaction is happening or not. Because that means that there could bemillions of people carrying multiple copies of the alpha tryptase gene, it should come as no surprise that some people will have more than one explanation for their symptoms. Anyone from the U.S. can register with this free program funded by NIH.

These symptoms may include allergic-like symptoms such as skin itching, flushing, hives, and even anaphylaxis; gastrointestinal (GI) symptoms such as bloating, abdominal pain, diarrhea and/or constipation (frequently diagnosed as irritable bowel syndrome or IBS), heartburn, reflux, and difficulty swallowing; connective tissue symptoms such as hypermobile joints and scoliosis; cardiac symptoms such as a racing or pounding heartbeat or blood pressure swings sometimes with fainting; as well as anxiety, depression, chronic pain, panic attacks, and others. Mast cells may play a role in protecting us from parasites but also can contribute to allergic responses by releasing molecules such as histamine in response to allergens. A mast cell is a cell that is made in the bone marrow and is associated with allergic reactions; it matures in places like the skin, lungs, and gastrointestinal tract. Dermatologists may collect skin samples to help diagnose a condition. Everyone has mast cells and although they are helpful, they are also important culprits in allergic reactions . It should not be drawn immediately after a major allergic reaction, as that can lead to an elevated tryptase for a different reason. The genetic defect is a copy number increase in the TPSAB1 gene but only when it encodes alpha tryptase.
