Abstract

The Enhancing NeuroImaging Genetics through Meta‐Analysis copy number variant (ENIGMA‐CNV) and 22q11.2 Deletion Syndrome Working Groups (22q‐ENIGMA WGs) were created to gain insight into the involvement of genetic factors in human brain development and related cognitive, psychiatric and behavioral manifestations. To that end, the ENIGMA‐CNV WG has collated CNV and magnetic resonance imaging (MRI) data from ~49,000 individuals across 38 global research sites, yielding one of the largest studies to date on the effects of CNVs on brain structures in the general population. The 22q‐ENIGMA WG includes 12 international research centers that assessed over 533 individuals with a confirmed 22q11.2 deletion syndrome, 40 with 22q11.2 duplications, and 333 typically developing controls, creating the largest‐ever 22q11.2 CNV neuroimaging data set. In this review, we outline the ENIGMA infrastructure and procedures for multi‐site analysis of CNVs and MRI data. So far, ENIGMA has identified effects of the 22q11.2, 16p11.2 distal, 15q11.2, and 1q21.1 distal CNVs on subcortical and cortical brain structures. Each CNV is associated with differences in cognitive, neurodevelopmental and neuropsychiatric traits, with characteristic patterns of brain structural abnormalities. Evidence of gene‐dosage effects on distinct brain regions also emerged, providing further insight into genotype–phenotype relationships. Taken together, these results offer a more comprehensive picture of molecular mechanisms involved in typical and atypical brain development. This “genotype‐first” approach also contributes to our understanding of the etiopathogenesis of brain disorders. Finally, we outline future directions to better understand effects of CNVs on brain structure and behavior.

  • Subcortical differences in 15q11.2 CNV deletion carriers appear restricted to decreased volume in the accumbens.

    “In contrast, subcortical differences appear restricted to decreased volume in the accumbens.”

    From Linking haploinsufficiency of the autism- and schizophrenia-associated gene Cyfip1 with striatal-limbic-cortical network dysfunction and cognitive inflexibility (2024) · cites this paper as [72]

    The “Summary and implications of the findings” section says the nucleus accumbens is altered in 15q11.2 deletion carriers but not duplication carriers. Our copy does not state there that its volume is decreased or that it is the only subcortical difference in deletion carriers; Figure 4’s caption identifies the comparison but gives no values. Page numbers were unavailable in the indexed copy. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • Differences in frontal and accumbens morphology in 15q11.2 CNV deletion carriers were associated with reduced cognitive flexibility on the Trial Making Task (B).

    “These differences in frontal and accumbens morphology were associated with reduced cognitive flexibility on the Trial Making Task (B) [72, 73].”

    From Linking haploinsufficiency of the autism- and schizophrenia-associated gene Cyfip1 with striatal-limbic-cortical network dysfunction and cognitive inflexibility (2024) · cites this paper as [72]

    The ‘Other CNVs’ section (page not provided) reports poorer cognitive performance and frontal cortical differences in 15q11.2 deletion carriers. It does not link those morphological differences to cognitive flexibility or report a Trail Making Task B result; its accumbens findings concern other CNVs. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • 15q11.2 CNV deletion carriers show dysfunctional connectivity in fronto-striatal circuitry and widespread differences in brain morphology throughout the cortex, including the frontal and cingulate cortices.

    “Dysfunctional connectivity in fronto-striatal circuitry is supported by evidence in 15q11.2 CNV deletion carriers with widespread differences in brain morphology seen throughout the cortex, including the frontal and cingulate cortices.”

    From Linking haploinsufficiency of the autism- and schizophrenia-associated gene Cyfip1 with striatal-limbic-cortical network dysfunction and cognitive inflexibility (2024) · cites this paper as [72]

    The “Other CNVs” section reports widespread differences in cortical surface area and thickness in 15q11.2 deletion carriers, particularly in the frontal lobe and anterior cingulate (page unavailable). It does not report dysfunctional fronto-striatal connectivity in those carriers; its mention of white-matter alterations does not establish that specific claim. (LLM, conf=0.90)

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.
