Abstract:
Assay has been made for ABO, Rh, Lewis, MNS and Duffy blood groups in a sample consisted of 80 affected individuals with chronic myelogenous leukemia (CML) and other sample consisted of 65 individuals affected with acute myelogenous leukemia (AML). Comparison have been made between each of the Leukemia sample with the control samples which consisted of 100 Healthy individuals.The results of the various comparisons were as follows : 1 - There is insignificant difference in frequency of ABO blood group in chronic and acute leukemia as compared with the control sample.2 - There are significant differences for Rh system patterns due to diminish of CcDee and ccDEe phenotypic patterns in both chronic and acute myelogenous leukemia, Moreover, there is an increase in CCDee pattern in CML and also an increase in CcDEe pattern in AML.3 - There are significant differences (P <0.001) for Lewis group blood in CML as compared with the control samples, also there is significant difference (P <0.05) in AML due to decrease in Le (a - b +) phenotype which resistant to the disease, and an increase in Le (a - b - ) phenotype.4 - There are significant differences (P <0.001) for MN blood group in both types of the disease (CML and AML), due to an increase in M + N + phenotype and decrease in M + N - phenotype. Also there is significant difference for Ss blood group in (AML), because of the increase in S + s + phenotype and decrease in S - s+ phenotype.5 - There is significant difference for Duffy group blood in CML, since the Fy (a + b - ) phenotype was decreased and the Fy (a - b +) was increased. But there is no significant difference in (AML).6 - There is no existence of disturbance or deviation in Hardy - Weinberg equilibrium for ABO, Rh and Lewis.7 - There is disturbance in Hardy - Weinberg equilibrium apparently existing for the MN blood group in both types of Leukemia as compared with the control sample . There is an increase in frequency of (N) allele in the patients and a decrease in frequency of (M) allele. There is also deviation (P <0.001) for Ss blood group in AML since allele S was increased ,but allele s was decreased in the patients as compared with the control sample .Moreover , there is deviation from this equilibrium for Duffy group blood in the overall Leukemia sample. The higher frequency of Fy ͣ allele was found in AML, while the higher frequency of Fyb and Fy alleles were found in CML . Such deviations from Hardy - Weinberg equilibrium in hematological malignancies and not deviated in the control sample may give attention about the etiology of the disease concerned.
