Comments: Reported as a β95 (FG2) Lys>Asn [AAG>AAC or AAT] change by amino acid analysis in a female subject from India without hematological abnormalities. The variant Hb was detected by cellulose acetate electrophoresis and column chromatography on DEAE-Sephadex. It was shown to migrate between Hb A and Hb J Baltimore. Could not be detected by electrophoresis on citrate agar gel. Hb stability tests and oxygen affinity studies were normal.
