Germline alterations of transcription factors in acute leukemia

In collaboration with the University Hospital of Lille, the team coordinated by Cyril Broccardo, identified the PAX5R38H mutation in a family in which all three children developed acute type B lymphoblastic leukemia (B-ALL). PAX5 is a central factor in the production of functional B cells and is often somatically altered in B-ALL. The team showed that the PAX5R38H mutant loses PAX functionality, thus blocking B cells at very early stages, but reacquires properties that may explain the initiation of leukemia. This transformation requires an alteration of the Ras and Jak/Stat pathways. Read the article
