Abstract

Holoprosencephaly (HPE; 1 out of 16,000 live births; 1 out of 250 conceptuses) is a complex brain malformation resulting from incomplete cleavage of the prosencephalon, affecting both the forebrain and the face. Clinical expressivity is variable, ranging from a single cerebral ventricle and cyclopia to clinically unaffected carriers in familial dominant autosomic HPE. The disease is genetically heterogeneous, but additional environmental agents also contribute to the etiology of HPE. In our cohort of 200 patients, 34 heterozygous mutations were identified, 24 of them being novel ones: 13 out of 17 in the Sonic hedgehog gene (SHH); 4 out of 7 in ZIC2; and 7 out of 8 in SIX3. The two mutations identified in TGIF have already been reported. Novel phenotypes associated with a mutation have been described, such as abnormalities of the pituitary gland and corpus callosum, colobomatous microphthalmia, choanal aperture stenosis, and isolated cleft lip. This study confirms the great genetic heterogeneity of the disease, the important phenotypic variability in HPE families, and the difficulty to establish genotype-phenotype correlations.

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?

  • TGIF1 and SIX3 are associated with abnormal cortical development in holoprosencephaly.

    “Similarly, two genes associated with abnormal cortical development in holoprosencephaly, TGIF1 and SIX327, are also enriched in cortical germinal zones.”

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.
