Patients can have various symptoms ranging from flushing, pruritis, autonomic dysfunction, GI dysmotility to even anaphylaxis. Phenotypically, these deletions result in 4 categories of disease expression: -Deletion of 1 alpha-chain: Silent carrier state, with a normal phenotype, -Deletion of 2 alpha-chains: Alpha-thalassemia trait (alpha-1 thalassemia), with mild hematologic changes but no major clinical difficulties, -Deletion of 3 alpha-chains: Hemoglobin H disease, which is extremely variable but usually includes anemia due to hemolysis, jaundice, and hepatosplenomegaly, -Deletion of all 4 alpha-chains: Hemoglobin Bart, with hydrops fetalis and almost invariably in utero demise.

Some individuals may demonstrate an increase in tryptase concentrations above baseline after anaphylaxis or allergen challenge while remaining below 11.5 ng/mL; measurement of tryptase in specimens obtained 1 to 6 hours and at least 24 hours after the episode may be useful in demonstrating a transient increase in concentrations. 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. Patient organizations can help patients and families connect. Exception for elevated bilirubin secondary to Gilberts disease. High levels of tryptase increase your risk of anaphylaxis.
