Comments: Reported as a de novo mutation in a 2-month-old infant girl, presented with persistent jaundice and failure to thrive. The infant was diagnosed with β-thalassemia. This mutation results in a stop-codon substitution to a tyrosine residue and an increase of 21 amino-acids in the β-globin chain that probably makes the protein unstable. Leads to a dominant beta-thalassemia state according to this case report.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
