Association between polymorphism of RAD50 gene and acute lymphoid leukemia in children / 中国当代儿科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the association between single nucleotide polymorphism (SNP) (rs17166050) in RAD50 gene and acute lymphoid leukemia (ALL) in children.</p><p><b>METHODS</b>A total of 177 ALL children from Wuhan and surrounding areas and 232 healthy children were selected. The numbers of standard-risk, medium-risk, and high-risk children were 66, 69, and 42, respectively. The genotypes of SNP in RAD50 gene were determined using PCR-RFLP, and the relationship of the RAD50 polymorphism with ALL susceptibility and clinical risk was analyzed.</p><p><b>RESULTS</b>The genotype (AA, GA, and GG) distribution of SNP in RAD50 gene showed significant differences between the ALL and control groups (P=0.038), and G allele was significantly associated with ALL susceptibility (OR=1.459, 95% CI 1.034-2.057, P=0.031). However, the SNP was not associated with the risk stratification of ALL.</p><p><b>CONCLUSIONS</b>The SNP (rs17166050) in RAD50 gene is associated with the susceptibility to ALL in children, but is not associated with the risk stratification of ALL.</p>
