A new hemoglobin variant: Hb Dagestan alpha 60(E9) Lys leads to Glu

An electrophoretically I-like hemoglobin variant was detected during a survey for abnormal hemoglobins in Dagestan (USSR). Neither clinical nor hematological abnormalities were seen in the carrier for this mutant hemoglobin. Structural studies demonstrated a previously undescribed substitution of alpha 60 (E9) Lys leads to Glu.
