Abstract

Given increasing numbers of patients who are undergoing exome or genome sequencing, it is critical to establish tools and methods to interpret the impact of genetic variation. While the ability to predict deleteriousness for any given variant is limited, missense variants remain a particularly challenging class of variation to interpret, since they can have drastically different effects depending on both the precise location and specific amino acid substitution of the variant. In order to better evaluate missense variation, we leveraged the exome sequencing data of 60,706 individuals from the Exome Aggregation Consortium (ExAC) dataset to identify sub-genic regions that are depleted of missense variation. We further used this depletion as part of a novel missense deleteriousness metric named MPC. We applied MPC to de novo missense variants and identified a category of de novo missense variants with the same impact on neurodevelopmental disorders as truncating mutations in intolerant genes, supporting the value of incorporating regional missense constraint in variant interpretation.

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

  • Using MPC score ≥2, 8% of de novo missense variants are predicted deleterious and are enriched 1.88-fold in affected offspring, comparable with dnLGD enrichment (p-value = 9.9 × 10−4).

    “Using a more strict D-mis prediction algorithm with MPC score ≥2,11 8% of de novo missense variants are predicted as deleterious and are enriched 1.88-fold in affected offspring which is comparable with the enrichment of dnLGD variants (p-value = 9.9 × 10−4 by one-sided exact Poisson test).”
  • Missense variants and protein-truncating variants differ in their impact on protein function.

    “missense variants and protein-truncating variants (PTVs) vary in their impact on protein function3–6.”
  • Existing methods for detecting gene-specific enrichment of damaging de novo mutations ignore much prior information about which variants are more likely disease-associated.

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.
