Identification of a circular RNA isoform of WASHC2A as a prognostic factor for high-risk paediatric B-ALL patients.

Pediatric B-cell acute lymphoblastic leukemia (B-ALL) is a serious disease for which a better understanding of prognostic factors and new therapeutic targets is needed. Circular RNAs (circRNAs) are promising markers due to their stability and differential expression patterns in various diseases. However, their role in pediatric B-ALL patients, particularly in risk stratification and relapse prediction, remains poorly understood.
