Abstract

To evaluate evidence for de novo etiologies in schizophrenia, we sequenced at high coverage the exomes of families recruited from two populations with distinct demographic structures and history. We sequenced a total of 795 exomes from 231 parent-proband trios enriched for sporadic schizophrenia cases, as well as 34 unaffected trios. We observed in cases an excess of de novo nonsynonymous single-nucleotide variants as well as a higher prevalence of gene-disruptive de novo mutations relative to controls. We found four genes (LAMA2, DPYD, TRRAP and VPS39) affected by recurrent de novo events within or across the two populations, which is unlikely to have occurred by chance. We show that de novo mutations affect genes with diverse functions and developmental profiles, but we also find a substantial contribution of mutations in genes with higher expression in early fetal life. Our results help define the genomic and neural architecture of schizophrenia.

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

  • CHD2, SYNGAP1, and SYNCRIP are also affected by LoF de novo SNVs in ID, and SYNGAP1 and DPYD are altered in schizophrenia.

    “Three other genes affected by de novo CNVs (also picked by NETBAG)—CHD2, SYNGAP1, and SYNCRIP—are also affected by LoF de novo SNVs in ID,50,52 and two (SYNGAP1 and DPYD [MIM 612779]) are altered in schizophrenia.53”
  • The authors did not find evidence of dURV enrichment in DPYD (two dURVs in cases, six in controls) or DISC1 (one in cases, two in controls).

    “We did not find any evidence of enrichment of dURVs in DPYD19 (in which we found two dURVs in cases and six in controls), nor in DISC120 (one dURV among cases and two in controls) (Supplementary Table 3).”

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.
