Comments: : Found in a 5-month-old female presented with severe congenital anaemia (Hb 5.9 g/dL, RBC 3.17×10^12/L) and moderate microcytosis (MCV 60.5 fL) and hypochromia (MCH 18.8 pg). The patient had transfusion-dependent β0-thalassaemia. The 2bp deletion, causing a frameshift that introduces a premature stop codon twenty amino acids further down the new reading frame.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
