Abstract

Significance: Gene targets of de novo mutation in autistic children have a lighter load of rare disruptive variation than typical human genes. This finding suggests such mutations are under negative selection and autism genes are highly vulnerable to mutation. Disruptive variants in these genes have biased transmission: They are more frequently transmitted to affected children, and more often from mothers than from fathers. Targets of mutation in lower intelligence quotient (IQ) affected children have a lower load of disruptive mutations than targets of mutation in higher IQ affected children. Biased transmission is seen more frequently to affected children of lower IQ. These observations are consistent with a correlation between severity of mutations and phenotype, and based on them, we list candidate autism genes ordered by likelihood.

  • The paper relies on this without support.

    The majority of LGD mutations, and the subset of nonsense mutations, are harmful.

    “The majority of LGD mutations (and the subset of nonsense) will be harmful, but this scenario is not so for missense mutations.”
  • The authors state this as an assumption.

    Noncontributory DN LGD mutations in affected children occur at same rate as DN LGD mutations in unaffected individuals, and their target genes have similar UR LGD loads.

    “The rate of noncontributory DN LGD mutations per affected individual should match the rate of DN LGD mutations in unaffected individuals; moreover, the genes targeted by noncontributory DN LGD mutations in affected and unaffected siblings should have similar loads of UR LGD mutations.”
  • The authors state this as an assumption.

    Vulnerability of noncausal genes is 1, i.e., they have same load as targets of DN LGD mutation in unaffected siblings.

    “where the vulnerability of noncausal genes is set to 1, reflecting the assumption that they have the same load as the targets of DN LGD mutation in unaffected siblings.”
  • The authors state this as an assumption.

    Autism vulnerable genes and intolerant (protected) genes are treated as the same set.

    “We developed a simple heuristic gene score based on the naive assumption that the set of autism vulnerable genes and the set of intolerant (protected) genes are the same.”
  • The authors state this as an assumption.

    DN and rare parental data are independent.

    “Using the Bayes rule, and further assuming that the DN and rare parental data are independent, we can rewrite this conditional probability as:”
  • The authors state this as an assumption.

    A protected gene has only 10% of typical share of UR LGD mutations.

    “To define pðRjAÞ, we assume that a protected gene has only 10% of the typical share of UR LGD mutations:”

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.

A language model drew the claims from the paper on 2026-10-06, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-06 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

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.
