Infant high-grade gliomas appear clinically distinct from their counterparts in older
children, indicating that histopathologic grading may not accurately refl ect the
biology of these tumors. We have collected 241 cases under 4 years of age, and carried out histologic
review, methylation profi ling, and custom panel, genome, or exome sequencing. After excluding tumors
representing other established entities or subgroups, we identifi ed 130 cases to be part of an “intrinsic” spectrum of disease specifi c to the infant population. These included those with targetable MAPK
alterations, and a large proportion of remaining cases harboring gene fusions targeting ALK ( n = 31),
NTRK1/2/3 ( n = 21), ROS1 ( n = 9), and MET ( n = 4) as their driving alterations, with evidence of effi cacy
of targeted agents in the clinic. These data strongly support the concept that infant gliomas require a
change in diagnostic practice and management. Infant high-grade gliomas in the cerebral hemispheres com..... READ ARTICLE
