Abstract

Extreme corneal fragility and thinning, which have a high risk of catastrophic spontaneous rupture, are the cardinal features of brittle cornea syndrome (BCS), an autosomal-recessive generalized connective tissue disorder. Enucleation is frequently the only management option for this condition, resulting in blindness and psychosocial distress. Even when the cornea remains grossly intact, visual function could also be impaired by a high degree of myopia and keratoconus. Deafness is another common feature and results in combined sensory deprivation. Using autozygosity mapping, we identified mutations in PRDM5 in families with BCS. We demonstrate that regulation of expression of extracellular matrix components, particularly fibrillar collagens, by PRDM5 is a key molecular mechanism that underlies corneal fragility in BCS and controls normal corneal development and maintenance. ZNF469, encoding a zinc finger protein of hitherto undefined function, has been identified as a quantitative trait locus for central corneal thickness, and mutations in this gene have been demonstrated in Tunisian Jewish and Palestinian kindreds with BCS. We show that ZNF469 and PRDM5, two genes that when mutated cause BCS, participate in the same regulatory pathway.

  • Because not all BCS patients harbored ZNF469 mutations, a second locus for BCS was suspected, and this was confirmed by the discovery of mutations in PRDM5.

    “Because not all BCS patients harbored ZNF469 mutations, a second locus for BCS was suspected.This was confirmed by the discovery of mutations in PRDM5 (MIM 614161) [Burkitt Wright et al., 2011].”

  • Keratoconus has also been diagnosed in a young adult heterozygous for a PRDM5 mutation.

  • To provide a comprehensive overview of the clinical phenotype of BCS, the authors reviewed data on 51 patients (ZNF469: n=32; PRDM5: n=19).

    “To provide a comprehensive overview of the clinical phenotype of BCS, we reviewed the data on 51 patients (ZNF469: n¼ 32; PRDM5: n ¼ 19) (Table S1) [Al-Hussain et al., 2004;Abu et al., 2008;Christensen et al., 2010;Khan et al., 2010;Burkitt Wright et al., 2011;Al-Owain et al., 2012;Aldahmesh et al., 2012;Rohrbach et al., 2013;Ramappa et al., 2014;Avgitidou et al., 2015b;Porter et al., 2015].”

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.
