Increased risk of Thai childhood acute lymphoblastic leukemia with the MiR196a2 T > C polymorphism

| Summary: | Objectives: This study assessed associations of the miR196a2 (rs11614913) T > C polymorphism withsusceptibility to childhood acute lymphoblastic leukemia (ALL) and clinical outcomes. Materials and Methods: Blood DNA samples from 104 childhood ALL patients and 180 healthy children were studied for the miR-196a2 (rs11614913) polymorphism using a polymerase chain reaction-restriction fragment-length polymorphism (PCR-RFLP) approach. Results: The frequency of the miR-196a2 (rs11614913) T allele in controls was 0.51 compared with 0.33 in ALL cases. In this study, CC, TC heterozygote and CC/TC genotypes were significantly associated with increase childhood ALL susceptibility compared with the TT wild type (OR =4.321, 95% CI = 2.091-8.930 p=0.000, OR = 2.248, 95% CI =1.103-4.579, p=0.024, OR = 2.921, 95% CI = 1.504-5.673 p=0.001, respectively). However, the miR-196a2 (rs11614913) T > C polymorphism was not associated with demographic data or clinico-pathological data in ALL cases. Conclusion: CC, TC and CC+TC genotypes of miR-196a2 (rs11614913) was significantly associated with increased susceptibility in Thai childhood ALL but not with clinical variables. |
