NUDT15 and acute lymphoblastic leukemia: These findings suggest that AS-PCR can determine NUDT15 diplotype and identify patients with compound heterozygous NUDT15 variants, which may enable precise genetic diagnosis of NUDT15. Nevertheless, a larger clinical trial is required to understand the clinical significance of NUDT15*3/*6 in pediatric patients with ALL because of its low incidence rate and challenges in detecting this variant.
