FGFR1 SV-altered gliomas were significantly more likely to be from younger patients of American or European ancestry (P <2.2 × 10−16, = 0.007, and = 0.002, respectively; Supplementary Table S3, available at https://doi.org/10.1016/j.esmoop.2022.100641) and less likely to be from tumors of a local origin (P = 3.3 × 10−8), versus unaltered gliomas. Here, FGFR1 is linked to glioma.
