Also known as:

Comments: Found in two Chinese patients with hypochromic microcytic anemia. The substitution results in a premature termination codon at codon 130 generating a truncated β-chain and causing the dominant β-thalassaemia trait.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
