Abstract: | The Human Leukocyte Allele (HLA) Class I (A, B, C) and Acute Lymphoid Leukemia and Myeloid Leukemia association, was determined by polymerase chain reaction--sequence specific primers (PCR-SSP) in 60 patients and 30 healthy controls. The results were reported as allelic frequencies and haplotype. The Chi-square corrected, Fisher's Test, Relative risk and etiologic fraction were calculated. A significant positive association was showed between HLA-B*39 (RR = 16.184; p = 0.0237) and HLA C*03 (RR = 5.0; p = 0.0127) alleles and Mycloid Leukaemia. Positive associations between haplotypes 2 loci: HLA-A*02-C*03 (RR = 6.0; p = 0.0153), A*24-C*03 (RR = 16.184; p = 0.0237), B*40-C*03 (RR = 10.706; p = 0.0021) and haplotype 3 loci: HLA-A*02-B*40-C*03 (RR = 8.11; p = 0.0102) and Myeloid Leukemia were found. No association was evident in Acute Lymphoid Leukemia. No negative association with Leukemias were observed. |
