WebDec 1, 2024 · The Fy(a–b–) phenotype, most commonly found in Black individuals, occurs primarily as a result of a GATA promoter region mutation upstream of the FY allele [1]. This mutation prevents the expression of Duffy glycoprotein on erythrocytes while permitting it on nonerythroid cells [ 2 ]. WebDec 18, 2024 · Hi NocolaBM, There is no doubt that the individuals with the Fy (a-b-) phenotype, who have the FYB gene and are homozygous for the GATA-1 mutation very rarely produce an anti-Fy3, but every now and again, you may come across one who does. I came across at least two examples of this when I was working in RCI at NHSBT-Tooting … WebDec 1, 2024 · The Fy(a–b–) phenotype, most commonly found in Black individuals, occurs primarily as a result of a GATA promoter region mutation upstream of the FY allele [1]. … holiday inn express gulf shores beachfront
