Also known as:
Comments: Found as a de novo mutation in a compound heterozygous state with Hb E in a transfusion-dependent 1-year-old child presenting with β-thalassaemia major complications. The mother was a heterozygous carrier of Hb E and the father was evaluated as normal. Paternity was confirmed. The loss of a nt G from codon 8 changes the reading frame with a stop codon at codon 18 resulting in a premature termination of translation.
We follow the HGVS sequence variant nomenclature and IUPAC standards.
