Acute lymphoblastic leukemia (ALL)

5ʹ-Nucleotidase cytosolic II (NT5C2)

In vitro studies suggest inhibiting NT5C2 could help treat chemotherapy-resistant ALL. In the first study, whole-exome sequencing of 103 relapsed T cell and 35 B cell ALL samples identified 21 with mutations in NT5C2 that increased nucleotidase activity and were absent at diagnosis. In the second study, gain-of-function mutations in NT5C2 were identified in 2 of 10 pediatric patients with B cell ALL at relapse that were absent at diagnosis and in 5 of 61 additional relapsed samples in a follow-up study. Next steps include developing diagnostic assays to identify the mutations and developing NT5C2 inhibitors.
