TERT and Miyoshi myopathy: In their complex work, Newell et al. (2022) identified many other genetic associations e.g., NF1-mutated CM localized in the head and neck has the highest tumour mutation burden (TMB), AM and MM have a lower ratio of TMB but more amplifications and breakpoints in the genome in comparison to CM; TERT promoter mutations were more common in CM (84%) than in AM (10%) and MM (16%).
