GCC1 and Miyoshi myopathy: (see detailed baseline characteristics of the MM patients and healthy controls in Supplementary Table S3) The results indicated that the expression levels of tRF-Met-CAT-2-M4 and tRF-Gly-GCC-1-M3 were significantly downregulated in MM patients (p < 0.001), while the expression of tRF-SeC-TCA-1 was markedly upregulated (p < 0.001), consistent with the tsRNA sequencing results (Figures 7D–F).
