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.
