Implication

Retrospective case-control study examines HBB mutations and CAT polymorphisms in beta-thalassemia major, suggesting genetic risk factors in a local population.

Key Points

  • Characterize clinical, hematological, biochemical, and molecular profiles of β-thalassemia major in Al-Diwaniyah, Iraq.
  • Retrospective case-control study involving 100 transfusion-dependent patients and 50 healthy controls.
  • Assessment of HBB mutations and CAT polymorphisms alongside clinical and biochemical markers.
  • Genotyping for specific mutations such as IVSI-1, IVSI-6, and CD39, and CAT polymorphisms rs1001179 and rs7943316.
  • 69% of patients carried at least one HBB mutation, with IVSI-1 at 29% and IVSI-6 at 25.5%.
  • Patients had significantly lower RBC, HGB, HCT, HDL, LDL, and CAT levels compared to controls (p < 0.001).
  • CAT polymorphism rs1001179 associated with increased disease risk (p = 0.019), while rs7943316 was not.
