Long-term survival of a baby with homozygous alpha-thalassemia-1

Area of Science:

• Genetics
• Hematology
• Pediatrics

Background:

• Alpha-thalassemia is a genetic blood disorder characterized by reduced or absent synthesis of alpha-globin chains.
• Homozygous alpha-thalassemia-1, also known as hemoglobin Bart's hydrops syndrome, is typically lethal in utero or shortly after birth due to severe anemia and hydrops fetalis.

Observation:

• A case of triplets born to a Chinese woman included a female infant diagnosed with hemoglobin Bart's hydrops syndrome.
• Gene analysis confirmed the infant was homozygous for alpha-thalassemia-1.
• The affected infant survived for 27 months, a rare occurrence for this condition.

Findings:

• This report details the third known case of homozygous alpha-thalassemia-1 with long-term survival.
• The case highlights the potential for extended survival despite the severe implications of the genetic mutation.

Implications:

• This case provides valuable insights into the management and potential therapeutic strategies for severe forms of alpha-thalassemia.
• Further research into the factors contributing to long-term survival in hemoglobin Bart's hydrops syndrome is warranted.
• Understanding long-term survival can inform genetic counseling and clinical management for affected families.
