Also known as:

Comments: Found in a 12-year-old Chinese boy in compound heterozygosity with HBB:c.126_129delCTTT [IthaID:147] and the -α4.2 [IthaID:301]. Patient presented with severe β-thalassemia and required regular blood transfusions. The A deletion caused a frameshift at codon 104, which resulted in an elongated protein of 156 amino acid residues.
