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.

Note:
The impact thresholds provided in this section are based on the analyses performed in Tamana et.al. For any given tool, the impact thresholds defined for the set of variants with the same effect on function as the variant examined, are preferred over those defined for the full dataset.
