Frequencies of ABO, Rhesus (D), Kpa and Kpb Blood Group Antigens in Al-Halfaween Sudanese Tribe

Abstract

This is descriptive, prospective analytical study conducted from March to June 2007, to determine the frequencies of ABO, Rh (D), Kpa and Kpb .antigens among Al-Halfaween Sudanese tribe The study was carried out on 100 predetermined random blood samples, collected into EDTA containers from this tribe and the grand father has one .chance to be included in the study Samples were tested for the presence of ABO and Rhesus (D) antigens using slide method and for Kpa and Kpb antigens using ID-Gel micro typing .system The frequency of ABO showed that the O blood group was found to be most frequent with frequency of (55%), whereas the A blood group was found with intermediate frequency (24%) followed by B blood group with frequency of (17%) and the least common was found to be AB blood group (4%). The Rhesus (D) was found to be (96%).Kpb was found to be 100%, .while Kpa was not detected Data was entered, checked, and analyzed using SPSS, and compared to .other populations using Jacquard's similarity coefficient The results were compared with some Sudanese tribes and revealed similarities between some tribes such as Al-Mahas, Al-Shukria and Al- .Shuluk, which point to the common ancestry of most of Sudanese tribes When results were compared with other populations, revealed that the frequency of ABO was found to be close to people from African region such as Nigerian and Kenyan populations and far from Indian and British .populations The frequency of Rhesus D was found to be close to Nigerian population and Black Americans, and far from Kenyan, British and White Americans .population The frequency for Kell-3 and Kell-4 in Al-Halfaween Sudanese tribe was .found to be close to that found in Blacks of United states
