Because of the There is no commercially available test for the genetic duplication, and it cannot be identified through usual genetic testing including microarrays, whole exome sequencing, or whole genome sequencing. Both deletional and nondeletional (caused by point alterations) forms of alpha-thalassemia are found in individuals with Mediterranean ancestry. Basal tryptase concentrations greater than or equal to 11.5 mg/mL may be consistent with cutaneous mastocytosis. It appears that the more copies one inherits, the higher the blood tryptase level.
