Comments: The mutation was detected in an adult Thai female during prenatal diagnosis of thalassemia and hemoglobinopathies. DNA sequencing analysis of the whole β-globin gene revealed double mutations of Hb E (IthaID:88) and Hb Palmerston North (IthaID:880) in the same β-globin gene which could be confirmed by multiplex allele-specific amplification. Hb analysis showed an unusually low level of Hb E in heterozygotic form.
We follow the HGVS sequence variant nomenclature and IUPAC standards.

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.
