In certain circumstances, these control probes may detect other diseases or conditions for which this test was not specifically intended. Mastocytosis encompasses a heterogeneous group of diseases characterized by the presence of clonal mast cells (MCs) in tissues and symptoms of MC activation, including anaphylaxis. 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. Genetic specialists (geneticists) are trained to diagnose, treat, and manage patients with genetic changes, birth defects, or metabolic disorders. It should not be drawn immediately after a major allergic reaction, as that can lead to an elevated tryptase for a different reason. 3657-3657.

Also, discovering multiple food allergies and medication allergies and sensitivities. 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. In other cases, patients actually carrythree copies of TPSAB1 on a single chromosome. In addition to disease-related probes, the multiplex ligation-dependent probe amplification technique utilizes probes localized to other chromosomal regions as internal controls. However, a wide range of symptoms has been reported among individuals with the associated syndrome, many of which can be rather common, so it is difficult to know who has it from symptoms alone. The frequency of thalassemia is due to the protective advantage against malaria that it gives carriers.
