Abstract

Autism is a genetically complex neurodevelopmental syndrome in which language deficits are a core feature. We describe results from two complimentary approaches used to identify risk variants on chromosome 7 that likely contribute to the etiology of autism. A two-stage association study tested 2758 SNPs across a 10 Mb 7q35 language-related autism QTL in AGRE (Autism Genetic Resource Exchange) trios and found significant association with Contactin Associated Protein-Like 2 (CNTNAP2), a strong a priori candidate. Male-only containing families were identified as primarily responsible for this association signal, consistent with the strong male affection bias in ASD and other language-based disorders. Gene-expression analyses in developing human brain further identified CNTNAP2 as enriched in circuits important for language development. Together, these results provide convergent evidence for involvement of CNTNAP2, a Neurexin family member, in autism, and demonstrate a connection between genetic risk for autism and specific brain structures.

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

  • The fourth M12 hub (CNTNAP1) is a homologue of the autism susceptibility gene CNTNAP2.

    “while the fourth is a homologue of the autism susceptibility gene CNTNAP2 17 .”

    From Transcriptomic Analysis of Autistic Brain Reveals Convergent Molecular Pathology (2011) · cites this paper as [17]

    The opening summary (p. 1) reports evidence that CNTNAP2 is involved in autism, supporting its description as an autism-susceptibility gene. Our copy does not establish that CNTNAP1 is a homologue of CNTNAP2; a search for CNTNAP1 found no passage addressing that relationship. (LLM, conf=0.86)

  • Two common polymorphisms in a relatively circumscribed area of CNTNAP2 modulate language function in ASD and other conditions.

    “Two common polymorphisms in a relatively circumscribed area of CNTNAP2 have been shown to modulate language function in ASD and other conditions [59–61].”

    From Genetics of autism spectrum disorders (2011) · cites this paper as [59]

  • Common variants in CNTNAP2 have also been associated with ASD and specific-language impairment.

    “Common variants in CNTNAP2 have also been associated with ASD (49–51) and specific-language impairment (52).”
  • Genetic mutations identified in small numbers of people with autism have been generated in mice.

    “To incorporate construct validity for the various genetic mutations identified in small numbers of people with autism (12–21), these mutations have been generated in mice (22, 23).”

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.
