title: Hb Albany-GA or alpha 2(11)(A9)Lys leads to Asn beta 2.
abstract: A fast-moving alpha chain abnormal hemoglobin (Hb J) was observed in a black teenager from southern Georgia. Its quantity, i.e. the sum of Hb J and Hb J2, was 23.8%. Its presence did not cause any hematological or clinical abnormalities. Tryptic peptides from a digest of the alpha-J chain were separated by HPLC. Amino acid analysis of these peptides and sequence analysis of the abnormal T-2,3 nonapeptide identified a Lys leads to Asn substitution at position alpha 11(A9).
