Patient consents to a fresh bone marrow biopsy at screening (once all other entry criteria have been satisfied). It appears that the more copies one inherits, the higher the blood tryptase level.

Source: www.mayoclinic.org. Allergists / Immunologists are trained to diagnose, treat, and manage diseases that affect the immune system. J Clin Invest. . 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.
