HbE-beta-thalassemia associated with G6PD deficiency

Area of Science:

• Hematology
• Genetics
• Pediatrics

Background:

• Hemoglobin E (HbE) and beta-thalassemia are common inherited blood disorders.
• Glucose-6-phosphate dehydrogenase (G6PD) deficiency is another prevalent genetic condition.
• These conditions disproportionately affect populations from Southeast Asia.

Observation:

• A 6-year-old Mexican-American child presented with anemia, jaundice, and growth delay.
• Genetic testing revealed compound heterozygosity for HbE and beta-thalassemia, along with G6PD deficiency.
• The child's parents were carriers for these respective conditions.

Findings:

• The simultaneous presence of HbE, beta-thalassemia, and G6PD deficiency was confirmed in the child.
• This case illustrates a complex genetic interaction leading to severe anemia.
• The inheritance pattern involved heterozygous HbE from the father and beta-thalassemia and G6PD deficiency from the mother.

Implications:

• The co-occurrence of these three genetic disorders should be considered in the differential diagnosis of anemia in children.
• Increased awareness is crucial, especially with migration patterns from Southeast Asia to the United States.
• This case underscores the importance of genetic counseling and early diagnosis for inherited blood disorders.
