Hemoglobin C-I-A.

G R Honig, M Borders

    Acta Haematologica
    |January 1, 1980
    PubMed
    Summary
    This summary is machine-generated.

    A novel hemoglobin variant, Hemoglobin I (alpha 16 lys leads to glu), was found with hemoglobins C and A in a healthy Black American woman. This suggests potential preferential formation of a hybrid hemoglobin molecule.

    Area of Science:

    • Biochemistry
    • Hematology
    • Genetics

    Background:

    • Hemoglobinopathies are genetic disorders affecting hemoglobin structure or function.
    • Hemoglobin variants are identified through various chromatographic and electrophoretic techniques.

    Observation:

    • Four major hemoglobins were detected in erythrocytes of a Black American woman using DEAE-cellulose column chromatography.
    • Hemoglobin I (alpha 16 lys leads to glu) was identified alongside Hemoglobin C and Hemoglobin A.

    Findings:

    • The identified Hemoglobin I variant did not present with any clinical or hematologic disease.
    • Nearly 50% of alpha I-chains were found in association with beta C chains.
    • Evidence suggests preferential formation of the alpha I beta C hybrid hemoglobin.

    Implications:

    • This finding expands the known spectrum of hemoglobin variants.
    • Understanding hybrid hemoglobin formation can provide insights into globin chain interactions.
    • Further research may elucidate the functional and structural consequences of this specific alpha I beta C hybrid hemoglobin.
