Williams-Beuren Syndrome: A Model of Recurrent Genomic Mutation

Pérez Jurado, Luis Alberto·2003·Hormone Research in Paediatrics

Abstract

Williams-Beuren syndrome is a segmental aneusomy syndrome with manifestations affecting the vascular, connective tissue, endocrine and central nervous systems. Most patients show a similar heterozygous ∼1.5 Mb deletion at 7q11.23 that contains a number of reported genes. Deletion mapping in the few atypical patients with smaller deletions suggested that additive effects of haploinsufficiency for two or more genes might be necessary for the phenotype. Vascular stenoses are caused by haploinsufficiency at the elastin gene, while the genes responsible for the cognitive deficits are likely located at the telomeric edge of the deletion, including CYLN2 and GTF2I. Large region-specific segmental duplications predispose to misalignment and inter- or intrachromosomal unequal crossing-over causing the deletions. Atypical alleles at 7q11.23 such as inversions and deletions/insertions of large repeats, also generated through aberrant recombination between the local segmental duplications, are found in ∼35% of transmitting parents. Genomic instability at 7q11.23 is directly related to the genomic structure of the region.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Overall, the skull shape in mutant animals is reminiscent of the head shape seen in WBS, including a small upturned nose with flat nasal bridge, micrognathia (or mandibular hypoplasia), malocclusion, bi-temporal narrowing and prominent forehead.

  • The reduced parietal bone length and reduction and upward angulation of the nasal bones in MommeD10 mice are reminiscent of the decrease in volume of the parieto-occipital region and the appearance of the nose in WBS patients.

    “The reduced parietal bone length and the reduction and upward angulation of the nasal bones in these mice (Figure 8c, d) are reminiscent of the decrease in the volume of the parieto-occipital region and the appearance of the nose in WBS patients [34,35].”

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.
