Researchers investigating
pediatric low - grade gliomas (PLGG), the most common
type of
brain tumor in children, have discovered key biological differences in how mutated genes combine with other genes to drive this childhood cancer.
He continues to study cancer gene function in his Georgetown lab, and has recently identified a new cancer gene called STAG2 that is among the most commonly mutated genes in cancer, involved in causing bladder cancer,
pediatric bone
tumors, leukemias,
brain tumors, and other
tumor types.
