How is tumor mutational burden calculated
Web24 mei 2024 · There is a large variability in mutation burden among and within tumor types, ranging from just a few to thousands of mutations (20–22). Results from several studies have demonstrated that subsets of patients with high TMB exist across almost all cancer types ( 12 , 14 ). WebThe hallmarks of the resulting tumors are mismatch-repair deficiency (MMR-D) and an exceedingly high tumor mutational burden (TMB) . The latter is characterized by frameshift mutations and, in consequence, by functionally impaired proteins as well as elevated frequencies of non-synonymous mutations.
