Also known as:

Comments: Reported as a de novo mutation in a two-month-old patient, initially diagnosed with congenital dyserythropoietic anaemia. This mutation results in a stop-codon substitution to a serine residue and an increase of 21 amino-acids in the beta-globin chain. Leads to a dominant beta-thalassemia state according to this case report.
