Frequency of ABO &Rh Phenotype (DECec) in shaigia Ethnic Group – Khartoum

Abstract

This is a descriptive, prospective and analytical study aimed to determine the frequency of ABO, rhesus blood group antigens and phenotypes. Among Alshaigia ethnic group in Khartoum state. This study was conducted during the period of six month (February to august 2013), following informed consent, a total of 100 venous blood samples were collected in 2.5 ml EDTA blood container from un releated individuals. The samples were investigated for ABO blood group antigens by direct a slide method, while for the Rhesus blood group antigens the sample were tested by tube method, Du technique was performed for each Rh (D) negative sample. The result obtained from this study shawed that in ABO blood group system the O antigen was the commonest antigen with the frequency of (40%), followed by A antigen (36%), B antigen (20%) and the last common was AB antigen (4%). Blood group antigens the frequency of c antigen was (99%) which was the highest frequency followed by e antigen was (95%), D antigen (92%), C antigen (44%) and E antigen (23%) which was the lowest frequency. In conclusion; marked similarities between tribes could probability point to a common ancestry in very ancient days. Some changes from this could be seem in another Sudanese tribes could be explain by their wandering nature.There is a great, very lap between the linguistic classification of the major Sudanese tribes and this genetics based categorization. Considerable similarities exist between different Sudanese population linguistic similarities between different Sudanese populations that lead to the development of the linguistic classification closely over lap with some genetics markers.
