Also known as:
Comments: Reported in a homozygous state in beta-thalassaemia major patients. The mutation in codon 14 leads to the termination of the transcript within the same exon (codons 21-22) and subsequent activation of the NMD pathway, which degrades the mutated transcript preventing its translation.
We follow the HGVS sequence variant nomenclature and IUPAC standards.
