Subclonal variation in patients with pediatric T-lymphoblastic leukemia (T-ALL)

Variations in TP53 and KRAS genes indicate a particularly poor prognosis in relapsed pediatric T-ALL. We hypothesized that these variations might be subclonally present at disease onset and contribute to relapse risk. To test this, we examined 386 children diagnosed with T-ALL, including more than 100 patients who relapsed as well as matched non-relapsing controls.
