Also known as:
Comments: Hb E-Udon Thani is a form of Hb E-β-thalassaemia syndrome caused by a double mutation on a β-globin gene. Found as a heterozygote in a healthy proband with a history of constant hypochromic microcytosis without anaemia, resulting in elevated Hb A2 (5.7%) and an unusually low level of Hb E (3.1%).
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.
