Comments: Hb Arya was first described in an Iranian family in 1974. A recent report described Hb Arya in a Malaysian family. Both potentials were clinically asymptomatic. This abnormal haemoglobin has an electrophoretic mobility very close to that of Hb S, thereby mimicking an electrophoretic pattern of the Hb S carrier.
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.
