To determine the role of single nucleotide polymorphisms (SNPs) in noncoding RNAs in childhood acute lymphoblastic leukemia (ALL) subtypes. We screened all SNPs in 130 pre-miRNA genes to assess their role in the susceptibility of the most common subtypes of ALL: hyperdiploid and . In two independent cohorts, we found a significant association between rs10406069 in miR-5196 and the risk of developing hyperdiploid ALL.

Nowadays, more than 2500 miRNAs have been described, that regulate more than 50% of genes, including those involved in B-cell maturation, differentiation and proliferation.

However, the variants associated in the diverse studies were different.

After reviewing previous studies, we realized that the most significant associations were restricted to intron 3, but the mechanism(s) by which those SNPs affect ALL risk remain to be elucidated. Therefore, the aim of this study was to analyze the association between genetic variants of the intron 3 region of ARID5B and the incidence of B-ALL in a Spanish population.
