pubmed:abstractText
The erythrocyte chemokine receptor, a receptor for Plasmodium vivax, carries the antigens of the Duffy blood group system. Sequence analysis of reticulocyte RNA from individuals of known Duffy phenotype showed that the Fya antigen differs from the Fyb antigen as a result of a single nucleotide difference (A131 or G) encoding amino acid Gly44 (Fya) or Asp (Fyb) in the N-terminal extracellular domain of the glycoprotein. Evidence is presented for two different genetic backgrounds giving rise to the Fy(a-b-) phenotype. The most likely genetic mechanism in most individuals of the Fy(a-b-) phenotype is down-regulation of Duffy glycoprotein mRNA. However, the Duffy gene from a very rare Caucasian individual (AZ) with the Fy(a-b-) phenotype has a 14 base-pair deletion (nucleotides 287-301) resulting in a frameshift which introduces a stop codon and produces a putative truncated 118 amino acid protein. The occurrence of this mutation in an apparently healthy individual raises questions about the functional importance of the Duffy glycoprotein not only in normal erythrocytes but also in all human cells and tissues.
