Also known as:
Comments: Reported in a proband presenting with persistent microcytosis and hypochromia. The deletion of a nt G from codon 28 creates a shift in the reading frame with a premature stop codon at codon 48 (TGA). Residue 28 at the B helix of the α chain is part of the α1β1 interface, which plays a key role in the maintenance of the tertiary structure.
We follow the HGVS sequence variant nomenclature and IUPAC standards.
