Abstract

Angelman syndrome is a genetic disorder characterized by pervasive developmental disability with failure to develop speech. We examined the basis for severe language delay in patients with Angelman syndrome by diffusion tensor imaging. Magnetic resonance imaging/diffusion tensor imaging was performed in 7 children with genetically confirmed Angelman syndrome (age 70 ± 26 months, 5 boys) and 4 age-matched control children to investigate the microstructural integrity of arcuate fasciculus and other major association tracts. Six of 7 children with Angelman syndrome had unidentifiable left arcuate fasciculus, while all control children had identifiable arcuate fasciculus. The right arcuate fasciculus was absent in 6 of 7 children with Angelman syndrome and 1 of 4 control children. Diffusion tensor imaging color mapping suggested aberrant morphology of the arcuate fasciculus region. Other association tracts, including uncinate fasciculus, inferior fronto-occipital fasciculus, inferior longitudinal fasciculus, and corticospinal tract, were identifiable but manifested decreased fractional anisotropy in children with Angelman syndrome. Increased apparent diffusion coefficient was seen in all tracts except uncinate fasciculus when compared to control children. Patients with Angelman syndrome have global impairment of white matter integrity in association tracts, particularly the arcuate fasciculus, which reveals severe morphologic changes. This finding could be the result of a potential problem with axon guidance during brain development, possibly due to loss of UBE3A gene expression.

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.
