WT1 synonymous single nucleotide polymorphism rs16754 correlates with higher mRNA expression and predicts significantly improved outcome in favorable-risk pediatric acute myeloid leukemia: a report from the children's oncology group.

ABSTRACT:

Purpose

To analyze the prevalence and clinical implications of Wilms' tumor 1 (WT1) single nucleotide polymorphism (SNP) rs16754 in the context of other prognostic markers in pediatric acute myeloid leukemia (AML).

Patients and methods

Available diagnostic marrow specimens (n = 790) from 1,328 patients enrolled in three consecutive Children's Cancer Group/Children's Oncology Group trials were analyzed for the presence of SNP rs16754. SNP status was correlated with disease characteristics, WT1 expression level, and clinical outcome.

Results

SNP rs16754 was present in 229 (29%) of 790 patients. The SNP was significantly more common in Asian and Hispanic patients and less common in white patients (P < .001). SNP rs16754 was also less common in patients with inv(16) (P =
