The Frequency of ABO & Kell Blood Group (K1 & K2)Antigens & Phenotypes among Alhalanga Sudanese Tribe

Abstract

This study has been carried out among Alhalanga community in East Sudan, from June to August 2007, targeting those who are apparently healty. It aims at analyzing the frequencies of ABO and Kell antigens and phenotypes. Hundred blood samples were collected into EDTA blood containers (2.5ml) from unrelated donors of both sexes (76 males & 24 females) of Alhalanga 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 Statistical Package of Social Sciences (SPSS). The study showed that the O phenotype was the commonest with the frequency of (48%), followed by A (27%), B (22%) While the AB was the least common (3%). Rh (D) antigen was found with high frequency (82%). The results showed that there was no statistical significant association between the occurrence of Kell phenotypes (K1,K2) and gender , as well as phenotype of ABO blood group. In the Kell blood group system K2 was the commonest antigen with the frequency of (100%), while k1 antigen was with low frequency (13%). The phenotype K-K+ was found with the high frequency (89%), while K+K+ was found with low frequency (11%), but the phenotype K+K- was not found. The genotype K2 K2 was with high frequent (89%), K1K2 was found with low frequency (11%), and the genotype K1K1 was not found. The results obtained were compared with results of other Sudanese tribes which showed agreement with Alshuluk, Alhalfawein and Elnuer, disagreement with Almanaseer.
