| Abstract | ||
| Single nucleotide polymorphism (SNP) in multidrug resistance gene1 (MDR1) could alter the gene expression level and may have effect role in responses to drug therapy and diseases susceptibility. The aim of the present study is to investigate allele frequency in Iraqi healthy and acute myeloid leukemia (AML) patients to detect the susceptibility of C1236T genotype carrier to develop AML. Also the study aimed to correlate the expression level of MDR1 mRNA with MDR1 C1236T polymorphism in newly diagnosed AML patients to predict clinical outcomes at initial diagnosis. The results showed there was a significant difference in genotype and allele frequency with heterozygous CT in AML while appeared significant with CC wild type in healthy control. Both AML and control showed non-significant in allele frequency. In regard with gene expression the healthy control showed significantly high level of MDR1 mRNAs expression in CC genotype at position 1236 compared with CT and TT. Whereas MDR1 heterozygous 1236CT genotype was showed highly significant difference in MDR1 mRNA expression among AML patients. According to the clinical outcome status MDR1 C1236T genotype showed statistically high significant differences with low level of CC genotype compared to CT/TT genotype at initial diagnosis in NR patients, while CR group was showed non-significantly with MDR1 C1236T polymorphism. In conclusion healthy Iraq populations have predominantly CC genotype and appeared a protective genotype, while MDR1 1236CT/TT genotype were indicated affected genotype and associated with poor prognosis in de novo AML patients, while CC appeared good prognosis. | ||
