Abstract

MicroRNAs (miRNAs) bind to complementary sequences within the 3' untranslated region (UTR) of mRNAs from hundreds of target genes, leading either to mRNA degradation or suppression of translation. We found that a mutation in the seed region of miR-184 (MIR184) is responsible for familial severe keratoconus combined with early-onset anterior polar cataract by deep sequencing of a linkage region known to contain the mutation. The mutant form fails to compete with miR-205 (MIR205) for overlapping target sites on the 3' UTRs of INPPL1 and ITGB4. Although these target genes and miR-205 are expressed widely, the phenotype is restricted to the cornea and lens because of the very high expression of miR-184 in these tissues. Our finding highlights the tissue specificity of a gene network regulated by a miRNA. Awareness of the important function of miRNAs could aid identification of susceptibility genes and new therapeutic targets for treatment of both rare and common diseases.

  • 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”

    From Gain-of-function mutation of microRNA-140 in human skeletal dysplasia (2019) · cites this paper as [3]

    The main text (page unavailable) identifies a heterozygous point mutation in MIR184 associated with familial keratoconus and early-onset cataract, and reports that the mutant loses a tested miR-184 function. This supports an example within the multiply cited statement, but the paper does not establish that the affected individuals’ condition was congenital: it describes the cataract as early-onset.

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.
