Genome-wide association studies (GWAS) have advanced our understanding of susceptibility to B-cell precursor acute lymphoblastic leukemia (BCP-ALL); however, much of the heritable risk remains unidentified. Here, we perform a GWAS and conduct a meta-analysis with two existing GWAS, totaling 2442 cases and 14,609 controls. We identify risk loci for BCP-ALL at 8q24.21 (rs28665337, P = 3.86 × 10, odds ratio (OR) = 1.34) and for ETV6-RUNX1 fusion-positive BCP-ALL at 2q22.3 (rs17481869, P = 3.20 × 10, OR = 2.14). Our findings provide further insights into genetic susceptibility to ALL and its biology.
全基因组关联研究（GWAS）已经提高了我们对 B 细胞前体急性淋巴细胞白血病（BCP-ALL）易感性的理解；然而，大部分可遗传风险仍然未知。在这里，我们进行了 GWAS 并进行了两项现有 GWAS 的荟萃分析，共包括 2442 例病例和 14609 例对照。我们在 8q24.21 （rs28665337，P=3.86×10，优势比（OR）=1.34）和 2q22.3 （rs17481869，P=3.20×10，OR=2.14）处鉴定出 BCP-ALL 的风险位点和 ETV6-RUNX1 融合阳性 BCP-ALL 的风险位点。我们的研究结果进一步深入了解 ALL 的遗传易感性及其生物学特性。
