Diagnostic approaches for inherited hemolytic anemia in the genetic era

Area of Science:

• Hematology
• Genetics
• Molecular Biology

Background:

• Inherited hemolytic anemias (IHAs) are genetic disorders characterized by premature destruction of red blood cells (RBCs).
• RBC abnormalities leading to IHAs are broadly categorized into membranopathies, hemoglobinopathies, and enzymopathies.
• Traditional diagnosis relies on a combination of clinical symptoms and laboratory test results.

Purpose of the Study:

• To review the current concepts and strategies for the genetic diagnosis of IHAs.
• To highlight the application of advanced molecular technologies, such as next-generation sequencing (NGS), in IHA diagnostics.
• To discuss the preparation and potential for clinical implementation of these new molecular diagnostic approaches.

Main Methods:

• Review of existing literature on IHA diagnosis and genetic testing.
• Discussion of the role of germline mutations in the etiology of IHAs.
• Exploration of next-generation sequencing (NGS) as a first-line diagnostic method.

Main Results:

• Germline mutations in genes encoding RBC structural components are the primary cause of IHAs.
• NGS enables efficient identification of known and novel causative mutations in IHA patients.
• Molecular technologies offer a powerful approach for precise IHA diagnosis.

Conclusions:

• Genetic diagnosis is crucial for understanding and managing IHAs.
• Next-generation sequencing represents a significant advancement for the first-line diagnosis of IHAs.
• Transitioning molecular technologies into clinical practice is essential for improving patient care and outcomes.
