To figure out whether MYCT1 protein was mutated in clinical cancer samples, we referred the MYCT1 gene using the Catalogue Of Somatic Mutations In Cancer dataset, and found three point mutations (L68P, G79R and A88D) in the TM region in three clinical cancer patient samples respectively (sample name TCGA‐F4‐6460‐01, TCGA‐G5‐6641‐01, TCGA‐86‐6851‐01). Here, MYCT1 is linked to cancer.
