Frequencies of ABO, Rhesus and Kell (K1 and k2) Blood Group Antigens in Aljaafra Tribe in Sudan

Abstract

This is study was a cross sectional descriptive study conducted in Al- Gaafrah Sudanese tribe to determine the frequency of the ABO Rhesus, and Kell antigens. This study was conducted in a period of three months (from Jan. 2010 to March 30, 2010). It aimed to establish a data base an information base for the tribe to determine the extent of overlapping between them and other tribes after comparison. Blood was collected from the people after taking their consent. Samples were collected from one hundred people from the tribe (non-relatives) in a 2.5 ml EDTAcontainer to avoid blood clotting, all samples were examined to determine blood groups. The results of this study were that the percentage of frequency of functional groups of the blood system's ABO that clique functional O were the most frequent rate (40%), followed by A rate (% 32 (and B by (14%) was the clique functional AB is the least frequent rate (8%) . In the Rhesus system the results were that functional groups (D), (e), (c) is the most frequent has been attributed (94%), (82%), (75%) respectively. Where as the functional groups (C), (E) is the least frequent rate (66%), (20%), respectively. The results of the Kell system were: (3% K1), (k2% 98 ) of the studied population .
