  • Program Description

    This program will describe the structure, distribution, and clinical significance of the Duffy Blood Group System. Antibodies to Duffy antigens are usually clinically significant and have been reported to cause hemolytic disease of the fetus and newborn. The FY glycoprotein, atypical chemokine receptor 1 ACKR1 will be explored and altered expressions of the alleles will be defined. Case studies will demonstrate how antibodies in this blood group may be detected in the blood bank.

    Learning Objectives

    After participating in this educational activity, participants should be able to:

    • Describe the clinical significance of antibody formation to the Duffy antigens in clinical practice.
    • Explain the significance of the GATA promoter region mutation as it relates to individuals who appear Fy(a-b-).
    • Highlight the role of the Duffy glycoprotein in malarial infections.
    • Explore the functional aspects of the FY Glycoprotein, ACKR1.
    • Apply the known serologic characteristics of the antibodies in the Duffy system to resolve complex serologic case studies.
