Abstract

OBJECTIVE: The authors used a custom array of 1,536 single-nucleotide polymorphisms (SNPs) to interrogate 94 functionally relevant candidate genes for schizophrenia and identify associations with 12 heritable neurophysiological and neurocognitive endophenotypes in data collected by the Consortium on the Genetics of Schizophrenia. METHOD: Variance-component association analyses of 534 genotyped subjects from 130 families were conducted by using Merlin software. A novel bootstrap total significance test was also developed to overcome the limitations of existing genomic multiple testing methods and robustly demonstrate significant associations in the context of complex family data and possible population stratification effects. RESULTS: Associations with endophenotypes were observed for 46 genes of potential functional significance, with three SNPs at p<10(-4), 27 SNPs at p<10(-3), and 147 SNPs at p<0.01. The bootstrap analyses confirmed that the 47 SNP-endophenotype combinations with the strongest evidence of association significantly exceeded that expected by chance alone, with 93% of these findings expected to be true. Many of the genes interact on a molecular level, and eight genes (e.g., NRG1 and ERBB4) displayed evidence for pleiotropy, revealing associations with four or more endophenotypes. The results collectively support a strong role for genes related to glutamate signaling in mediating schizophrenia susceptibility. CONCLUSIONS: This study supports use of relevant endophenotypes and the bootstrap total significance test for identifying genetic variation underlying the etiology of schizophrenia. In addition, the observation of extensive pleiotropy for some genes and singular associations for others suggests alternative, independent pathways mediating pathogenesis in the "group of schizophrenias."

  • The Research Domain Criteria project involves measurement of common physiological, neuropsychological, or brain imaging markers to identify a patient subgroup or alternately be themselves a target for treatment.

    “The Research Domain Criteria project (73,74) involves measurement of common physiological, neuropsychological, or brain imaging markers to identify a patient subgroup or alternately be themselves a target for treatment.”

    From Pediatric psychopharmacology: Too much or too little? (2013) · cites this paper as [74]

    The Introduction (page unavailable) describes measuring neurophysiological and neurocognitive endophenotypes and proposes that genes associated with them may serve as biomarkers for early identification and as treatment targets. It does not describe the Research Domain Criteria project or brain-imaging markers, and its proposed treatment targets are genes rather than the measured markers themselves. (LLM, conf=0.83)

  • NRG1 forms neuregulin.

    “Another related gene is NRG1 which forms neuregulin (28, 29).”
  • Both PPI and P50 deficits have been associated with entire networks of genetic variants in schizophrenia in the NIMH Consortium of Genetics Studies of Schizophrenia study.

    “As the scope of genomic analysis has increased, both deficits have been associated with entire networks of genetic variants in schizophrenia in the NIMH Consortium of Genetics Studies of Schizophrenia study, which examines the relationships of these phenotypes to the cognitive and genetic aspects of schizophrenia (28).”

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.
