Abstract

Most previously reported mutations in cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) result in an odd number of cysteine residues within the epidermal growth factor (EGF)-like repeats in Notch3. We report here R75P mutation in two Japanese CADASIL families not directly involving cysteine residues located within the first EGF-like repeats. Probands in both families had repeated episodes of stroke, depression, dementia as well as T2 high-intensity lesions in the basal ganglia and periventricular white matter, but fewer white matter lesions in the temporal pole on MRI. These families provide new insights into the diagnosis and pathomechanisms of CADASIL.

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

  • Clinical and radiological presentations in CADASIL depend on genotype.

    “Likely contributing to this variability, growing evidence suggests that the clinical and radiological presentations in CADASIL are dependent on the genotype [26, 35, 44–46, 61, 62].”
  • Anterior temporal involvement appears less common in subjects with cysteine-sparing NOTCH3 mutations, although the role of cysteine-sparing mutations in CADASIL pathogenesis remains debated.

    “For example, anterior temporal involvement appears to be less common in subjects with cysteine-sparing NOTCH3 mutations, although the role of cysteine-sparing mutations in the pathogenesis of CADASIL remains a matter of debate [26, 35, 44–46, 62].”

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.
