Abstract

The genomes of individuals with severe, undiagnosed developmental disorders are enriched in damaging de novo mutations (DNMs) in developmentally important genes. Here we have sequenced the exomes of 4,293 families containing individuals with developmental disorders, and meta-analysed these data with data from another 3,287 individuals with similar disorders. We show that the most important factors influencing the diagnostic yield of DNMs are the sex of the affected individual, the relatedness of their parents, whether close relatives are affected and the parental ages. We identified 94 genes enriched in damaging DNMs, including 14 that previously lacked compelling evidence of involvement in developmental disorders. We have also characterized the phenotypic diversity among these disorders. We estimate that 42% of our cohort carry pathogenic DNMs in coding sequences; approximately half of these DNMs disrupt gene function and the remainder result in altered protein function. We estimate that developmental disorders caused by DNMs have an average prevalence of 1 in 213 to 1 in 448 births, depending on parental age. Given current global demographics, this equates to almost 400,000 children born per year.

  • Exome studies identify a higher frequency of disruptive de novo variants in severe NDD than in ASD.

    “exome studies identify a higher frequency of disruptive de novo variants in severe NDD than in ASD (Deciphering Developmental Disorders Study, 2017)”

    From Large-Scale Exome Sequencing Study Implicates Both Developmental and Functional Changes in the Neurobiology of Autism (2020) · cites this paper as Deciphering Developmental Disorders Study, 2017

    The paper’s Abstract reports exome sequencing in severe developmental disorders and enrichment for damaging de novo mutations, with approximately half of estimated pathogenic coding mutations disrupting gene function. It does not report a frequency comparison with ASD; ASD studies appear in the References, but those entries do not establish the claimed higher frequency. (LLM, conf=0.85)

  • A similar sex effect in severe developmental disorders is entirely explained by a relatively small number of DD genes.

    “However, a similar effect is observed in severe developmental disorders more generally and is entirely explained by a relatively small number of genes significantly associated with severe developmental disorders (that is, DD genes)48.”

  • 93 developmental disorder risk genes with genome-wide significance were obtained from the Deciphering Developmental Disorders Study.

    “Genes that harbor de novo protein disrupting variation in developmental disorders (DD) were obtained from the Deciphering Developmental Disorders Study (93 DD risk genes with genome-wide significance)64.”
  • The ID/DD cohorts evaluated in the Satterstrom and Coe studies overlapped almost completely; each study used samples from five previously published studies, and four of the five were the same studies, accounting for 99% of the samples.

    “In fact, the ID/DD cohorts evaluated in these two studies overlapped almost completely; each study used samples from five previously published studies, and four of the five were the same studies, accounting for 99% of the samples.11, 12, 13, 14, 15, 16”

  • Reduced reliance on multiplex pedigrees in favour of collections of affected cases, often with parents, has been decisive in identifying new dominant disorders, many previously considered recessive.

    “Reduced reliance on multiplex pedigrees in favour of collections of affected cases, often with parents13, has proven decisive in identifying new dominant disorders, many of which were previously considered recessive14.”

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.
