    Abstract

    MicroRNAs (miRNAs) bind to complementary sites in their target mRNAs to mediate post-transcriptional repression, with the specificity of target recognition being crucially dependent on the miRNA seed region. Impaired miRNA target binding resulting from SNPs within mRNA target sites has been shown to lead to pathologies associated with dysregulated gene expression. However, no pathogenic mutations within the mature sequence of a miRNA have been reported so far. Here we show that point mutations in the seed region of miR-96, a miRNA expressed in hair cells of the inner ear, result in autosomal dominant, progressive hearing loss. This is the first study implicating a miRNA in a mendelian disorder. The identified mutations have a strong impact on miR-96 biogenesis and result in a significant reduction of mRNA targeting. We propose that these mutations alter the regulatory role of miR-96 in maintaining gene expression profiles in hair cells required for their normal function.

      • Related Citations
        Calculated set of PubMed citations closely related to the selected article(s) retrieved using a word weight algorithm. Related articles are displayed in ranked order from most to least relevant, with the “linked from” citation displayed first.
      • Gene
        Gene records that cite the current articles. Citations in Gene are added manually by NCBI or imported from outside public resources.
      • Gene (GeneRIF)
        Gene records that have the current articles as Reference into Function citations (GeneRIFs). NLM staff reviewing the literature while indexing MEDLINE add GeneRIFs manually.
      • Gene (OMIM)
        Gene records associated with Online Mendelian Inheritance in Man (OMIM) records that cite the current articles in their reference lists.
      • Nucleotide (RefSeq)
        NCBI nucleotide Reference Sequences (RefSeqs) that are cited in the current articles, included in the corresponding Gene Reference into Function, or that include the PubMed articles as references.
      • OMIM (calculated)
        Online Mendelian Inheritance in Man (OMIM) records that include the current articles as references in the light bulb links within or in the citations at the end of the OMIM record. The references available through the light bulb link are collected using the PubMed related articles algorithm to identify records with similar terminology to the OMIM record.
