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.

  • Point mutations within the seed region of miR-96 cause autosomal dominant non-syndromic sensorineural hearing loss in two Spanish families and in a mouse model of NSHL.

    “Recently, point mutations within the seed region of miR-96 were reported in two Spanish families with autosomal dominant non-syndromic sensorineural hearing loss (NSHL) and in a mouse model of NSHL.”
  • The MIR96 mutation reported here is the third mutation described in this gene in humans and the first in a population different from that of the original report.

    “This is the third mutation described in this gene in humans, and the first in a different population from that of the original report (14).”
  • Mutations within miR-96 are not a common cause of deafness.

    “Even though mutations within miR-96 are not a common cause of deafness, as evidenced by this and previous works (14,17), the description of novel causative variants might help in elucidating the pathogenic mechanisms underlying the DFNA50-associated phenotype.”
  • Heterozygous loss-of-function point mutations of miRNA genes are associated with several human congenital disorders.

    “Heterozygous loss-of-function point mutations of miRNA genes are associated with several human congenital disorders1–5”
  • Besides gene dosage abnormalities, single nucleotide substitutions in two miRNA genes have been identified in human diseases: MIR96 mutations in autosomal dominant deafness 50 and MIR184 mutations in EDICT syndrome and familial and sporadic cases of keratoconus.

    “Besides gene dosage abnormalities37,38, single nucleotide substitutions in two miRNA genes have been identified in human diseases: MIR96 mutations in autosomal dominant deafness 50 (#613704) and MIR184 mutations in EDICT syndrome (#614303) and familial and sporadic cases of keratoconus1–5,39.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
