Unusual phenotype of hemoglobin EE with hemoglobin H disease: a pitfall in clinical diagnosis and genetic counseling.

Abstract excerpt

Two unrelated individuals previously diagnosed as hemoglobin (Hb) EE were found to be, in fact, Hb EE with Hb H disease. This globin genotype normally results as Hb EF Bart disease. This unusual genotype-phenotype interaction highlights the need for molecular analysis in affected individuals with Hb E disorders before appropriate genetic counseling and genetic risk estimation in offspring can be given.
