Surface plasmon resonance-based molecular detection of Hb S [beta6(A3)Glu-->Val, GAG-->GTG] at the gene level.

abstract：:A new unstable hemoglobin (Hb) variant, named Hb Aalesund, was detected during Hb A1c measurement in a patient with a nearly compensated hemolytic anemia. Sequencing of the α-globin genes revealed a 7 bp deletion in exon 3 of the HBA2 gene (HBA2: c.400_406delAGCACCG) (NM_000517.4) causing a frameshift and a premature ...
