Gene associated with seizures, autism, and hepatomegaly in an Amish girl
Abstract
A genetic defect causing autism and epilepsy involving the contactin associated protein-like 2 gene (CNTNAP2) has been discovered in a selected cohort of Amish children. These children were found to have focal seizures and autistic regression. Surgical biopsy of the anterior temporal lobe of two such children revealed cortical dysplasia and a single nucleotide polymorphism mutation of this gene. The present case is that of a related but geographically distant proband with a similar phenotype but a single-base-pair deletion in the CNTNAP2 gene. This patient exhibited the additional features of periventricular leukomalacia and hepatomegaly.

Rare variation in CNTNAP2, including CNVs, other structural disruptions and deleterious sequence variation, has been identified in subjects with autism, epilepsy, intellectual disability, Pitt-Hopkins-like syndrome, schizophrenia and Tourette syndrome.
“More directly, rare variation in CNTNAP2, including CNVs, other structural disruptions and deleterious sequence variation, has been identified in subjects with autism, epilepsy, intellectual disability, Pitt-Hopkins-like syndrome, schizophrenia and Tourette syndrome (42–48), albeit with differing degrees of evidence for effect on these traits.”

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.
