The β-goblin gene architecture in individuals with and without sickle cell disease in Nigeria: Implications for β-thalassaemia trait diagnosis

OBOluwatoyin A. BabalolaBBBiobele J. BrownFFFoluke Fasola

Key Points

  • Molecular confirmation shows a low prevalence of β-thalassaemia trait in Yoruba individuals, emphasizing the need for accurate tests.
  • Two rare variants were identified, including a β-thalassaemia mutation on a minor haplotype, adding to genetic diversity knowledge.
  • Limitations of high-performance liquid chromatography for diagnosing β-thalassaemia are underscored, indicating a reliance on genetic testing.
  • Genetic testing may enable more accurate diagnosis and management of β-thalassaemia trait in populations with sickle cell disease.

Abstract

This study provides the first molecular confirmation of the low prevalence of β-thalassaemia trait in the Yoruba population. It identifies two rare variants, including a β-thalassaemia mutation on a minor, atypical haplotype, and highlights the limitations of high-performance liquid chromatography, underscoring the importance of genetic testing for accurate diagnosis.
