- Description
- 71 Childhood B-cell acute lymphocytic leukemia relapse patients had their diagnosis and relapse samples sequenced for NT5C2 mutations. Sequencing revealed 3 early relapse cases with NT5C2 R238W enriched at relapse at variant allele frequencies (VAF) of 27%, 18%, and 31% and only a VAF of .01%, 0%, and 0% at diagnosis. R238W could drive clonal outgrowth through the promotion of drug resistance, specifically to thiopurines, which are a staple of ALL maintenance therapy that are administered daily.
