The ABO and Kell phenotypes and their frequencies among Arrakein Sudanese ethnic group

Abstract

The ABO system was the first to be recognized and remain the most important. Kell is one of the important blood group system on human erythrocyte. This study was aimed at determining the frequency of Kell-1 and Kell-2 phenotypes in Arrakien population. The study was carried out in 100 predetermined random samples; from Arrakien tribe and the grand father has one chance to be included in the study. Samples were tested for the presence of ABO using slide method and for K1 and K2 using ID- Gel Micro typing system which contain coated anti- K1 and anti-K2 antisera. The samples were collected from Tyba Elshekh Abdalbagi and Abu Haraz areas. Result was showing that: The frequency of ABO , A blood groupwas found to be 30%, B was 27%, O was 39% and AB was found to be 4%. Kell-1 was found to be 2%, while Kell-2 was found to be 98%. The conclusion of the study was that: The frequencies of ABO was found tobe close to that found in people from African race( Nairobian and Nigerian populations) and far from that found in United states and Mexico populations. The frequency for Kell 1 in the Arrakien population was found to be close to that found in Blacks of United states populations . and Negroes of Brazil ,and it was far away from that found in Arabian and English populations, and Kell-2 was found close to the studies that done to Pakistani and English populations.
