Abstract
Capillary Electrophoresis plays an important role in the diagnosis of hemoglobinopathy carriers and patients. The general flow is the determination of the red blood cell indices to establish a microcytic hypochromic anemia and Hb-typing by separation and quantitation of the different hemoglobin fractions. DNA analysis is the final confirming step to complete the diagnosis. In the era of Next Generation Sequencing, many genetic labs have employed Whole Exome Sequencing and Inherited Disease panels as tools to analyze DNA and detect disease causing mutation. However, functional assays are considered to be important to establish the function and effects of variants of uncertain significance. Functional assays in hemoglobinopathies are the hematology and the Hb-typing, either by Capillary Electrophoresis or HPLC, to be completed by DNA analysis as will be demonstrated during the talk.
Learning Objectives
- Describe the basic construction, genetics, and inheritance of Hemoglobin and Hemoglobinopathies.
- Describe the clinical impact of several hemoglobinopathies and the importance of prevention and management.
- Demonstrate the three part flowchart of Hemoglobinopathy screening, including Capillary Electrophoreisis and HPLC techniques.
- Demonstrate the use of the screening flowchart through several high-complexity examples of clinically significant hemoglobinopathies.
