One, 2, 3, or 4 alpha-globin genes may be deleted or, less commonly, contain variants. Levels of total tryptase in serum greater than or equal to 11.5 ng/mL may indicate mast cell activation occurring as a result of anaphylaxis or allergen challenge, or it may indicate increased number of mast cells as seen in patients with mastocytosis. Downs SM, van Dyck PC, Rinaldo P, et al. 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.
