Neonatal DNA methylation and early-onset conduct problems: A genome-wide, prospective study / Charlotte A. M. CECIL in Development and Psychopathology, 30-2 (May 2018)
[article]
Titre : Neonatal DNA methylation and early-onset conduct problems: A genome-wide, prospective study Type de document : Texte imprimé et/ou numérique Auteurs : Charlotte A. M. CECIL, Auteur ; Esther WALTON, Auteur ; Sara R. JAFFEE, Auteur ; Tom O'CONNOR, Auteur ; Barbara MAUGHAN, Auteur ; Caroline L. RELTON, Auteur ; Rebecca G. SMITH, Auteur ; Wendy MCARDLE, Auteur ; Tom R. GAUNT, Auteur ; Isabelle OUELLET-MORIN, Auteur ; Edward D. BARKER, Auteur Article en page(s) : p.383-397 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Early-onset conduct problems (CP) are a key predictor of adult criminality and poor mental health. While previous studies suggest that both genetic and environmental risks play an important role in the development of early-onset CP, little is known about potential biological processes underlying these associations. In this study, we examined prospective associations between DNA methylation (cord blood at birth) and trajectories of CP (4–13 years), using data drawn from the Avon Longitudinal Study of Parents and Children. Methylomic variation at seven loci across the genome (false discovery rate < 0.05) differentiated children who go on to develop early-onset (n = 174) versus low (n = 86) CP, including sites in the vicinity of the monoglyceride lipase (MGLL) gene (involved in endocannabinoid signaling and pain perception). Subthreshold associations in the vicinity of three candidate genes for CP (monoamine oxidase A [MAOA], brain-derived neurotrophic factor [BDNF], and FK506 binding protein 5 [FKBP5]) were also identified. Within the early-onset CP group, methylation levels of the identified sites did not distinguish children who will go on to persist versus desist in CP behavior over time. Overall, we found that several of the identified sites correlated with prenatal exposures, and none were linked to known genetic methylation quantitative trait loci. Findings contribute to a better understanding of epigenetic patterns associated with early-onset CP.

SMITH in Molecular Autism, (March 2014)
[article]
Titre : Transcriptomic changes in the frontal cortex associated with paternal age Type de document : Texte imprimé et/ou numérique Auteurs : Rebecca G. SMITH, Auteur ; Cathy FERNANDES, Auteur ; Rachel KEMBER, Auteur ; Leonard C. SCHALKWYK, Auteur ; Joseph D. BUXBAUM, Auteur ; Abraham REICHENBERG, Auteur ; Jonathan MILL, Auteur Article en page(s) : p.1-7 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Advanced paternal age is robustly associated with several human neuropsychiatric disorders, particularly autism. The precise mechanism(s) mediating the paternal age effect are not known, but they are thought to involve the accumulation of de novo (epi)genomic alterations. In this study we investigate differences in the frontal cortex transcriptome in a mouse model of advanced paternal age.
