Platzgummer S, Bizzaro N, Bilo MB, et al: Recommendations for the use of tryptase in the diagnosis of anaphylaxis and clonal mastcell disorders. Upon mast cell activation, degranulation releases mature tryptase, which is almost exclusively in the form of beta-tryptase. Transfusion and/or erythropoietin not permitted within 1 week prior to blood draw. Less frequently, alpha-thalassemia results from single point alterations, such as hemoglobin Constant Spring (HBA2: c.427T >C). This disorder has likely been present for many generations within specific families, and, while our judgment is only based on the patients we have seen, having multiple alpha alleles appears compatible with long, productive lives. The fluorescence is directly proportional to the concentration of tryptase in the serum specimen. Future research will be dedicated to identifying symptoms and populations commonly associated with hereditary alpha tryptasemia and finding a treatment that specifically targets alpha tryptase and its mechanisms of action to better advise and manage those who carry multiple alpha genes.

Often, multiple specialists are needed to diagnose and care for a person with a rare disease. Though many rare diseases do not have a cure, research is ongoing and new treatments are constantly being developed. Many doctors have limited experience diagnosing rare diseases. The types of therapy offered will vary depending on the therapist's specific training program. 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.
