Frequency of ABO & Kell Blood Group Antigens & Phenotypes Among ALmanaseer Sudanese Ethnic Group

Abstract

This community- based prospective and analytical study was carried out among Almnaseer tribe in northern Sudan during 6-8 /2007 and aimed to determine the frequencies of ABO and Kell phenotypes. Hundred samples were collected into EDTA blood containers (2.5ml) from unrelated donors of both sexes (59 males & 41 females) of Almnaseer individuals; all samples were investigated by direct agglutination ABO and Gell technique to detect Kell system phenotypes(k1,k2). Data were analyzed by the computer using SPSS program. The results showed that the frequency of A blood groups was 23%, B 18%, O 56%, and AB 3%. The frequency of Kell (K1) antigen was (+ve 73%, -ve 27%) and K2 antigen was (+ve 96%, -ve 4%). The study showed that there is no statistical significant association between the occurrence of Kell phenotypes (K1,K2) and gender , as well as phenotype of ABO blood group. The results obtained were compared with results of other Sudanese tribes which showed agreement with some(such as Alshuluk tribe) and disagreement with others.
