Duffy phenotypes in Malaysian populations: correction of previous unusual findings.
Duffy phenotypes were determined for 314 Malaysian Orang Asli. The most common gene, Fya, was present in 313; there were no Duffy negative individuals. A previous study found evidence of Plasmodium vivax infection in 5 of 7 Orang Asli reported to be of the Duffy negative genotype. In this study, 5 of the 7 previously tested Orang Asli were retested in triplicate, and each of the 5 was found to be Duffy positive, having the Fya gene and a phenotype of Fy (a + b-).
