Bogatikov et al. (2019) identified 13 dysregulated miRNAs (11 upregulated and 2 downregulated) in the omohyoid muscle of mice with MuSK-Ab-positive EAMG. Among these differentially expressed miRNAs, miR-1930-5p and miR-1933-3p had a greater effect on the expression of target genes than other miRNAs, including Impa1 (inositol monophosphatase I) and Mrpl27 (mitochondrial ribosomal protein L27). In addition to these two miRNAs, let-7a-5p, let-7f-5p, mir-151a-3p, and mir-423-5p are specifically elevated in MuSK-Ab-positive MG patients (Punga et al., 2016). Here, MRPL27 is linked to myasthenia gravis.
