[Clinical practice guidelines for beta-thalassemia]

Area of Science:

• Genetics
• Hematology
• Medical Science

Background:

• Beta-thalassemia is an autosomal recessive genetic disorder, prevalent in tropical/subtropical regions like southern China.
• Molecular basis of beta-thalassemia was among the first single-gene disorders elucidated.
• Severe anemia in affected children often leads to early mortality without effective interventions.

Purpose of the Study:

• To provide practical guidance for clinicians and lab personnel on beta-thalassemia management.
• Focus on clinical diagnosis, genetic consultation, treatment, and population prevention strategies.
• Utilize phenotypic and genetic data from the Chinese population.

Main Methods:

• Review of clinical diagnosis and genetic consultation approaches.
• Summary of current and emerging treatment modalities.
• Analysis of population prevention strategies based on genetic data.

Main Results:

• Prenatal diagnosis is key for preventing beta-thalassemia.
• Long-term survival is achievable with standardized blood transfusions and iron chelation therapy.
• Hematopoietic stem cell transplantation offers a potential cure, and gene therapy shows promise.

Conclusions:

• Comprehensive management involving diagnosis, consultation, and treatment is crucial.
• Population prevention through genetic screening and counseling is vital.
• Advancements in stem cell and gene therapy present future treatment avenues.
