Summary

Two novel beta-thalassemia mutations were identified in a Sikh family in the UAE. A boy with compound heterozygosity underwent a successful bone marrow transplant from his sister.

Area of Science:

  • Genetics
  • Hematology
  • Molecular Biology

Background:

  • Beta-thalassemia is a significant inherited blood disorder.
  • Genetic mutations in the beta-globin gene cause beta-thalassemia.
  • Understanding mutation diversity is crucial for genetic counseling and treatment.

Purpose of the Study:

  • To report novel beta-thalassemia mutations found in a Sikh family in the United Arab Emirates.
  • To describe the clinical presentation and management of a child with compound heterozygous beta-thalassemia.

Main Methods:

  • Genetic sequencing to identify beta-thalassemia mutations.
  • Clinical evaluation of affected family members.
  • Bone marrow transplantation procedure.

Main Results:

  • Identified two new frameshift mutations: +ATCT at codons 47/48 in the father and +C at codons 57/58 in the mother.
  • Two daughters presented with beta-thalassemia trait.
  • A son with compound heterozygosity required transfusion support and underwent a successful bone marrow transplant.

Conclusions:

  • Novel beta-thalassemia mutations can arise in diverse ethnic populations.
  • Early diagnosis and timely intervention, including bone marrow transplantation, are vital for managing severe beta-thalassemia.
  • Genetic screening and counseling are important for families with inherited blood disorders.
