Abstract

BACKGROUND: Schizophrenia is a severe neuropsychiatric disorder that is hypothesized to result from disturbances ine arly brain development. There is mounting evidence to support a role for developmentally regulated epigenetic variation in the molecular etiology of the disorder. Here, we describe a systematic study of schizophrenia-associated methylomic variation in the adult brain and its relationship to changes in DNA methylation across human fetal brain development. RESULTS: We profile methylomic variation in matched prefrontal cortex and cerebellum brain tissue from schizophrenia patients and controls, identifying disease-associated differential DNA methylation at multiple loci,particularly in the prefrontal cortex, and confirming these differences in an independent set of adult brain samples.Our data reveal discrete modules of co-methylated loci associated with schizophrenia that are enriched for genes involved in neurodevelopmental processes and include loci implicated by genetic studies of the disorder. Methylomic data from human fetal cortex samples, spanning 23 to 184 days post-conception, indicates that schizophrenia-associated differentially methylated positions are significantly enriched for loci at which DNA methylation is dynamically altered during human fetal brain development. CONCLUSIONS: Our data support the hypothesis that schizophrenia has an important early neurodevelopmental component, and suggest that epigenetic mechanisms may mediate these effects.

  • EWAS studies have identified differential DNAm in HTR2A, HTR5A and HTR1E genes in those with psychosis.

    “Further, EWAS studies have identified differential DNAm in HTR2A (Numata, Ye, Herman, & Lipska, 2014), HTR5A and HTR1E (Nishioka et al., 2013; Pidsley et al., 2014) genes in those with psychosis.”

    From Can epigenetics shine a light on the biological pathways underlying major mental disorders? (2022) · cites this paper as Pidsley et al., 2014

    In Results and discussion, under identification of differentially methylated positions in the prefrontal cortex (page unavailable), the paper reports significantly different DNA methylation at HTR5A in schizophrenia patients versus controls. The cited Pidsley paper does not report an HTR1E finding in the passages retrieved for that gene. HTR2A is separately attributed to Numata et al. in the citing sentence, so it is not assessed against Pidsley. (LLM, conf=0.88)

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.
