Abstract

<abstract> <title>Abstract</title> <p>Poor prednisone response predicts an inferior outcome in pediatric acute lymphoblastic leukemia (ALL) in Berlin–Frankfurt–Münster (BFM) treatment protocols. Here, we investigated five single nucleotide polymorphisms (SNPs) in both the coding and non-coding regions of the glucocorticoid receptor (<italic>GR</italic>) gene, and analyzed their association with prednisone responsiveness <italic>in vivo</italic> in 63 pediatric patients with ALL in China. Of the five SNPs, the rs41423247 and rs7701443 polymorphisms were significantly associated with prednisone response at the allelic level (rs41423247 odds ratio [OR] = 9.58; 95% confidence interval [CI]: 1.23–74.21; <italic>p</italic> = 0.01; rs7701443 OR = 3.12; 95% CI: 1.08–9; <italic>p</italic> = 0.02). Two polymorphisms (rs6189/6190 and rs6198) were not observed in the study cohort. Haplotypes composed of <italic>CCC</italic> alleles and <italic>TCG</italic> alleles at three loci (rs7701443, Tth111I and <italic>Bcl</italic>I) were both associated with prednisone response (<italic>p</italic> = 0.013; <italic>p</italic> = 0.028). Our results suggested that polymorphisms in the non-coding region of the <italic>GR</italic> gene were associated with prednisone response <italic>in vivo</italic> in pediatric ALL in Han Chinese.</p> </abstract>
