| Abstract: | N6-methyladenosine (m6A) is the most abundant internal RNA modification in eukaryotes and plays a key role in cellular growth and development. Global changes in cellular methylated RNA and m6A-mediated transcript regulation significantly impact oncogenesis. Here, we investigate how recurrent synonymous and non-synonymous somatic mutations abolishing individual canonical methylated m6A motifs affect transcript levels and survival of patients with cancer. Moreover, we explore the effect of these mutations on creating de novo m6A motifs. To this end, we compared publicly available data on m6A sites with mutations reported in The Cancer Genome Atlas (TCGA). We find that mutations disrupting or creating m6A motifs display a low recurrence and have a negligible impact on RNA abundance. Patients with the highest number of disrupted m6A sites or newly generated m6A motifs did not generally exhibit alterations in mortality risk or outcomes. Hence, our data suggest that mutational alterations in the m6A motif landscape are unlikely to be a primary mechanism for regulating gene function across most cancer types. This may be attributed to the fact that mutations typically affect individual m6A sites, which is likely insufficient to significantly impact gene expression. © The Author(s) 2025.
