Abstract

Autism is a neurodevelopmental disorder of complex etiology in which genetic factors play a major role. We have implicated the neurexin 1 (NRXN1) gene in two independent subjects who display an autism spectrum disorder (ASD) in association with a balanced chromosomal abnormality involving 2p16.3. In the first, with karyotype 46,XX,ins(16;2)(q22.1;p16.1p16.3)pat, NRXN1 is directly disrupted within intron 5. Importantly, the father possesses the same chromosomal abnormality in the absence of ASD, indicating that the interruption of alpha-NRXN1 is not fully penetrant and must interact with other factors to produce ASD. The breakpoint in the second subject, with 46,XY,t(1;2)(q31.3;p16.3)dn, occurs approximately 750 kb 5' to NRXN1 within a 2.6 Mb genomic segment that harbors no currently annotated genes. A scan of the NRXN1 coding sequence in a cohort of ASD subjects, relative to non-ASD controls, revealed that amino acid alterations in neurexin 1 are not present at high frequency in ASD. However, a number of rare sequence variants in the coding region, including two missense changes in conserved residues of the alpha-neurexin 1 leader sequence and of an epidermal growth factor (EGF)-like domain, respectively, suggest that even subtle changes in NRXN1 might contribute to susceptibility to ASD.

  • The neurexin-1 (nrxn1) gene has been linked directly to ASD and SCZ.

    “Of these, the neurexin-1 (nrxn1) gene has been linked directly to ASD and SCZ (Kim et al. 2008; Rujescu et al. 2009, Glessner et al. 2009; Ching et al. 2010; Gauthier et al. 2011).”

    From Neurexin1α knockout in rats causes aberrant social behaviour: relevance for autism and schizophrenia (2025) · cites this paper as Kim et al. 2008

    The paper’s opening section (p. 1) implicates NRXN1 in autism spectrum disorder, supporting the ASD part of the claim. The copy does not link NRXN1 to schizophrenia (SCZ); a search for “schizophrenia” found no such passage. The other citations may support that part, but this verdict concerns Kim et al. only.

  • Mutations in some of these genes such as genes encoding cadherins and neurexin-neuroligins in human, which were differentially methylated following exposure to adverse maternal environment in mice, have been associated with ASD (179-182).

    “mutations in some of these genes such as genes encoding cadherins and neurexin–neuroligins in human, which were differentially methylated following exposure to adverse maternal environment in mice, have been associated with ASD (179–182).”
  • Shank2, SAPAP2, Neurexin-1, Neuroligin-3 and Neuroligin-4 have been implicated in human ASDs.

    “In addition to Shank39, it is worth noting that Shank26,8, SAPAP26, Neurexin-126, Neuroligin-3 and −427 have all been implicated in human ASDs.”
  • NRXN1 has previously been linked to ASD.

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.
