Abstract

Schizophrenia is a common disease with a complex aetiology, probably involving multiple and heterogeneous genetic factors. Here, by analysing the exome sequences of 2,536 schizophrenia cases and 2,543 controls, we demonstrate a polygenic burden primarily arising from rare (less than 1 in 10,000), disruptive mutations distributed across many genes. Particularly enriched gene sets include the voltage-gated calcium ion channel and the signalling complex formed by the activity-regulated cytoskeleton-associated scaffold protein (ARC) of the postsynaptic density, sets previously implicated by genome-wide association and copy-number variation studies. Similar to reports in autism, targets of the fragile X mental retardation protein (FMRP, product of FMR1) are enriched for case mutations. No individual gene-based test achieves significance after correction for multiple testing and we do not detect any alleles of moderately low frequency (approximately 0.5 to 1 per cent) and moderately large effect. Taken together, these data suggest that population-based exome sequencing can discover risk alleles and complements established gene-mapping paradigms in neuropsychiatric disease.

  • CYFIP1 regulation of calcium channel subunits compromises intracellular calcium levels, resulting in delayed axonal development.

    “These findings support our model in which CYFIP1 regulation of calcium channel subunits compromise intracellular calcium levels, resulting in delayed axonal development10,84,85 (Fig. 7).”

    From CYFIP1 governs the development of cortical axons by modulating calcium availability (2025) · cites this paper as [10]

    The Extended Data table lists a disruptive CYFIP1 variant, and the ‘ARC, PSD-95 and calcium ion channel genes’ section reports mutations in calcium-channel subunits. The Discussion proposes altered calcium-dependent signaling as a possibility. Neither passage shows that CYFIP1 regulates those subunits, changes intracellular calcium levels, or delays axonal development; those links are the citing authors’ model, not findings established by this source. (LLM, conf=0.78)

  • A rare heterozygous disruptive nonsense variant p.Arg624Ter in CYFIP1 was detected in a patient diagnosed with schizophrenia.

    “Additionally, a polygenic pattern including a rare heterozygous disruptive nonsense variant, p.Arg624Ter, in CYFIP1 was detected in a patient diagnosed with SCZ115 (Table 2n).”

    From The WAVE complex in developmental and adulthood brain disorders (2025) · cites this paper as [115]

    Extended Data Tables 3 and 8 report one singleton disruptive CYFIP1 variant in a schizophrenia case and none in controls. The passages do not identify it as p.Arg624Ter or establish that it was a heterozygous nonsense variant. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Common variation dominates heritable risk for schizophrenia and autism spectrum disorder.

    “direct comparisons of the contributions of common and rare genetic variation show that common variation dominates heritable risk for SCZ and ASD (Gaugler et al., 2014; Purcell et al., 2014)”
  • When directly examined, polygenic risk combines additively with major mutation burden.

    “In the instances where this has been studied directly, polygenic risk acts additively with major mutational burdens (Gaugler et al., 2014; Niemi et al., 2018; Purcell et al., 2014; Weiner et al., 2017).”
  • Many severe mutations do not converge on one specific phenotype but instead seem to cause a range of clinical disorders.

    “Thus, many severe mutations do not converge on one specific phenotype but instead seem to cause a range of clinical disorders74,76,80,81,84,87,91.”

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.
