Three identical alpha + thalassemia genes, one of which always carried the Hb J Tongariki mutation, have been observed in Vanuatuans. Despite the fact that at least two of them have arisen by different types of crossover event, the expression of all three haplotypes is identical.

Objectives: This study reported a large cohort of fetal blood analysis of various hemoglobinopathies.
Methods: A total of 371 fetal blood specimens were recruited. Complete blood count and hemoglobin (Hb) analysis using capillary electrophoresis were performed.

Individual enhancers are defined as short genomic regulatory elements, bound by transcription factors, and able to activate cell-specific gene expression at a distance, in an orientation-independent manner. Within mammalian genomes, enhancer-like elements may be found individually or within clusters referred to as locus control regions or super-enhancers (SEs). While these behave similarly to individual enhancers with respect to cell specificity, distribution and distance, their orientation-dependence has not been formally tested.

Unlabelled: Thalassemias and hemoglobinopathies are among the most common genetic diseases worldwide and have a significant impact on public health. The decreasing cost of next-generation sequencing (NGS) has quickly enabled the development of new assays that allow for the simultaneous analysis of small nucleotide variants (SNVs) and copy number variants (CNVs) as deletions/duplications of α- and β-globin genes.
Background/objectives: This study highlighted the efficacy and rapid identification of all types of mutations in the α- and β-globin genes, including silent variants, using the Devyser Thalassemia NGS kit.

Thalassemia is an inherited blood disorder and traditionally considered more prevalent in Southern China. However, with increased migration and intermarriage, more and more thalassemia carriers had been reported in Northern China. The lack of screening for thalassemia carriers may also result in missed diagnosis in Northern China.
View Article and Find Full Text PDFBackground: This study aimed to evaluate the efficacy of third-generation sequencing (TGS) and a thalassemia (Thal) gene diagnostic kit in identifying Thal gene mutations.
Methods: Blood samples (n = 119) with positive hematology screening results were tested using polymerase chain reaction (PCR)-based methods and TGS on the PacBio-Sequel-II-platform, respectively.
Results: Out of the 119 cases, 106 cases showed fully consistent results between the two methods, with TGS identified HBA1/2 and HBB gene mutations in 82 individuals.
