MUSK and myasthenia gravis: The top six significant miRNAs from the discovery set were validated using RT-qPCR, revealing four of them, i.e., miR-340-5p, miR-160b-5p, miR-27a-3p, and miR-15a-3p, as the most DE miRNAs in MuSK-MG patients compared to controls, although their levels did not correlate with anti-MuSK antibody titer or QMG scores [101].
