Abstract

To understand the genetic heterogeneity underlying developmental delay, we compared copy number variants (CNVs) in 15,767 children with intellectual disability and various congenital defects (cases) to CNVs in 8,329 unaffected adult controls. We estimate that ∼14.2% of disease in these children is caused by CNVs >400 kb. We observed a greater enrichment of CNVs in individuals with craniofacial anomalies and cardiovascular defects compared to those with epilepsy or autism. We identified 59 pathogenic CNVs, including 14 new or previously weakly supported candidates, refined the critical interval for several genomic disorders, such as the 17q21.31 microdeletion syndrome, and identified 940 candidate dosage-sensitive genes. We also developed methods to opportunistically discover small, disruptive CNVs within the large and growing diagnostic array datasets. This evolving CNV morbidity map, combined with exome and genome sequencing, will be critical for deciphering the genetic basis of developmental delay, intellectual disability and autism spectrum disorders.

  • About 0.25% of controls (n=66,462) are found with the 15q11.2 BP1-BP2 microdeletion.

    “a review of reported data from control cohorts (n = 66,462 subjects) summarized to date show that about 0.25% of controls are found with the 15q11.2 BP1–BP2 microdeletion [18,27,28,29,30,31].”

    From The 15q11.2 BP1–BP2 Microdeletion Syndrome: A Review (2015) · cites this paper as [27]

    The Results (Locus-specific enrichments; page unavailable) identify the 15q11.2 deletion and report its enrichment in cases relative to controls. The Discussion identifies it as the BP1–BP2 deletion. Neither passage gives the claimed 0.25% control frequency or a control cohort of 66,462; searches for both figures found no supporting passage in our copy. (LLM, conf=0.82)

  • Deletions and duplications of a chromosomal region including CYFIP1 have been linked to intellectual disability, autism spectrum disorder, and schizophrenia.

    “Deletions and duplications of a chromosomal region including CYFIP1 have been linked to ID, ASD, and schizophrenia (Cooper et al., 2011, Doornbos et al., 2009, Leblond et al., 2012, Murthy et al., 2007, Nowicki et al., 2007, Tam et al., 2010, van der Zwaag et al., 2010, von der Lippe et al., 2010, Zhao et al., 2012).”

    From CYFIP1 Coordinates mRNA Translation and Cytoskeleton Remodeling to Ensure Proper Dendritic Spine Formation (2013) · cites this paper as Cooper et al., 2011

    The Results (Locus-specific enrichments; page unavailable) report that 15q11.2 deletions are enriched among individuals with intellectual disability or developmental delay. Our copy does not name CYFIP1 or establish the claimed links for duplications at that locus. Its discussion of autism and schizophrenia concerns a different deletion, at 15q25.2. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • The 15q11.2 deletion is associated with developmental delay (OR 2.36).

    “developmental delay (OR 2.36),3”
  • CYFIP1 is implicated in intellectual disability, autism spectrum disorder, and schizophrenia.

    “CYFIP1 is implicated in ID (Cooper et al., 2011, Napoli et al., 2008, Nowicki et al., 2007, Schenck et al., 2003), ASD (Cooper et al., 2011, Doornbos et al., 2009, Murthy et al., 2007, Nishimura et al., 2007, Sahoo et al., 2006, van der Zwaag et al., 2010, von der Lippe et al., 2010), and SCZ (Tam et al., 2010, Zhao et al., 2012).”

    From CYFIP1 Coordinates mRNA Translation and Cytoskeleton Remodeling to Ensure Proper Dendritic Spine Formation (2013) · cites this paper as Cooper et al., 2011

    The Discussion reports pathogenicity of 15q11.2 deletions in affected individuals, and the Methods describe an ID/DD cohort that includes autism cases. But searches for CYFIP1 and its proposed links to ID and ASD found no passage identifying that gene or linking it to either condition. The citing sentence attributes schizophrenia to other sources, not Cooper et al. (LLM, conf=0.73)

    Experimental — accuracy not yet measured
  • 273 rare CNVs were identified in 206 affected offspring.

    “we identified 273 rare CNVs (occurring with a carrier frequency of ≤1% of the 1379 individuals in the analysis and also appear <1% in 1000 Genomes population and healthy controls18) in 206 affected offspring.”

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.
