RNF213 and multiminicore myopathy: RNF213 is not listed as a direct target of miR-512-3p in the miRNA database, and our limited sample size prevented us from comparing expression across different RNF213 genotypes; future multivariate miRNA panels and functional studies should incorporate RNF213 genotype to fully elucidate the molecular crosstalk driving MMD pathogenesis7,58–60.
