Conclusion

Alpha-thalassemias are common hemoglobinopathies, very heterogeneous at clinical and molecular level. Four different clinical conditions of increased severity have been described: the silent carrier state, alpha-thalassemia trait, HbH disease, and Hb Bart's hydrops fetalis syndrome. HbH disease is a moderate, very rarely severe, microcytic, and hypochromic hemolytic anemia, whereas Hb Bart's hydrops fetalis syndrome is a condition not compatible with postnatal life. Deletion defects are more common than nondeletion defects. The carrier state is suspected by hematological methods, but the precise identification is possible with several PCR-based procedures or globin chain synthesis analysis. Prenatal diagnosis is only indicated for Hb Bart's hydrops fetalis syndrome.
