Also known as:

Comments: Found in a mother with a history of transfusion-dependent thalassemia and also in her child presented with anemia and clinical data of thalassemia. The 4 bp insertion (GCAC), causes a frameshift that introduces a premature stop codon four amino acids further down the new reading frame.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
