Using the cBioportal data, we observed that across all tested tumor types (10,506 profiled samples in 27 solid TCGA tumor types), the frequencies of alterations (missense mutations, amplifications, deletions) in TIF1 member-encoding genes were relatively low (Figure S1A), with 2.6%, 2.2%, 1.8%, and 0.9% genetic alterations in profiled samples for TRIM24, TRIM28, TRIM33, and TRIM66, respectively. Here, TRIM28 is linked to neoplasm.
