While large studies of multiple different ethnicities need to be done, the estimate is that hereditary alpha tryptasemia may be present in a similar percentage of the general population. This includes cutaneous mastocytosis, systemic mastocytosis, mast cell activation syndromes, idiopathic anaphylaxis, and hereditary alpha tryptasemia. Tryptase, a neutral protease, is a dominant protein component of the secretory granules of human mast cells. Hereditary alpha-tryptasemia (HT) is an autosomal dominant genetic trait found in 4% to 6% of the general population and defined by excess copies of alpha-tryptase at TPSAB1.Elevated basal serum tryptase (sBT >8 ng/mL) is a defining feature of HT and appears to result from increased pro-alpha-tryptase synthesis and secretion rather than mast cell activation.

Types of PCPs include doctors practicing general medicine, family practice, pediatrics, internal medicine, and geriatrics. It is made primarily by cells that are present around blood vessels and in the bone marrow called mast cells, and it is used largely as a marker for mast cell activation, as it can be easily measured by a blood test, especially after certain allergic reactions. In some cases, both parents can carry the duplication, so that a child could have four copies. Mental health support is available for patients and caregivers who are coping with the stress that can come with having a rare disease. 19952023 Mayo Foundation for Medical Education and Research.

Symptomatic treatment targeting individual symptoms is the only route for management at present. called Hereditary Alpha Tryptasemia Syndrome and how he finds this in his patients with MCAS, having normal tryptase levels. Genetic specialists (geneticists) are trained to diagnose, treat, and manage patients with genetic changes, birth defects, or metabolic disorders. Send whole blood specimen in original tube. Finding 2: We had recently described Hereditary alpha tryptasemia syndrome (HATS), initially identified in over 50 families with an autosomal dominant inheritance of elevated basal tryptase levels in the absence of any signs of mastocytosis.
