Effect of untranslated repetitive RNA on expression of genes involved in DNA proofreading or replication–As an additional alternative, one may suggest that the untranslated repetitive RNA from the mutated DMPK gene interferes with the expression of genes involved in DNA proofreading and replication, thereby inducing both expansion of DNA repeats in the DMPK gene as well as mutations in cancer-driving genes. This evidence concerns the gene DMPK and cancer.
