Hb Fontainebleau (HBA2: c.64G > C) is a rare α-globin variant, which has previously been described in only 10 individuals worldwide. We report here 12 additional cases identified in our laboratory. These included the first case of a homozygosity for Hb Fontainebleau and cases in which Hb Fontainebleau occurred in combination with deletional and nondeletional α-thalassemia (α-thal). The prevalence of Hb Fontainebleau in the samples submitted to our laboratory for premarital hemoglobinopathy screening was 0.24%, the highest reported prevalence to date, indicating that this is a comparatively common variant in the United Arab Emirates (UAE).

α-Thalassemia is one of the most common monogenic diseases worldwide. The combination of alpha-chain variants with thalassemia mutations may lead to clinical and hematological characteristics, which is of importance for genetic counseling. The present study describes for the first time a rare α1-globin nonsense mutation, codon 99 (: c.

Objectives: To describe the laboratory features of haemoglobin Fontainebleau (Hb FB) and its interactions with various α and β globin gene mutations in the Omani population.
Methods: Over a period of 10 years, a total of 94 blood samples were suspected to have an α variant on HPLC at the Sultan Qaboos University Hospital, Muscat, Oman. Molecular testing was performed using PCR based techniques to define the variant and to analyse other interacting mutations in either α or β globin genes.

α-Thalassemia (α-thal) is one of the most common inherited hemoglobin (Hb) disorders in the world. In addition to large deletions, over 50 different α-thal point mutations were detected around the world, thus, patients showed different phenotypes with regard to genotype. This study evaluated the genetic frequency of α-thal in Khuzestan Province, Southwest Iran, to help implement premarital and prenatal screening programs.
