Two novel frameshift mutations in the HBA2 gene, associated with nondeletional alpha-thalassemia, were identified. These mutations alter protein structure and may contribute to severe thalassemia phenotypes.
Area of Science:
- Genetics
- Molecular Biology
- Hematology
Background:
- Nondeletional alpha-thalassemia accounts for approximately 10% of alpha-thalassemia cases.
- These mutations affect mRNA processing at transcriptional, translational, or post-translational levels.
- Most nondeletional alpha-thalassemias occur in the HBA2 gene without impacting HBA1 gene expression.

Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
