Tryptase, a neutral protease, is a dominant protein component of the secretory granules of human mast cells. In some cases, both parents can carry the duplication, so that a child could have four copies. In contrast, an amino acid change in alpha-protryptase prevents processing to a mature form.

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. Tryptase is an enzyme that is released by mast cells (along with histamine), and it is involved in activating more mast cells, increasing cytokine activity, and is even involved in connective tissue regeneration. A trait is simply a characteristic that is caused by a difference in the DNA. The type of lab tests ordered will depend on your symptoms and the diseases being considered.

These hospitals rely on a group of experts, often with diverse training. About Hereditary alpha tryptasemia syndrome. It is also possible that the increased tryptase itself causes the symptoms without requiring mast cells to be activated, or it could cause an abnormally increased response to otherwise normal mast cell activation, which might explain why so many patients respond to medications that target mast cells and substances released by mast cells. Collection Instructions: Submit confluent cultured cells from another laboratory. For any prenatal specimen that is received, maternal cell contamination studies will be added.
