Titre : Trajectories leading to autism spectrum disorders are affected by paternal age: findings from two nationally representative twin studies Type de document : Texte imprimé et/ou numérique Auteurs : Sebastian LUNDSTROM, Auteur ; Christopher GILLBERG, Auteur ; Henrik ANCKARSATER, Auteur ; Christina M. HULTMAN, Auteur ; Eva CARLSTROM, Auteur ; Abraham REICHENBERG, Auteur ; Jonathan MILL, Auteur ; Angelica RONALD, Auteur ; Robert PLOMIN, Auteur ; Maria RASTAM, Auteur ; Paul LICHTENSTEIN, Auteur ; Claire Margaret Alison HAWORTH, Auteur Année de publication : 2010 Article en page(s) : p.850-856 Langues : Anglais (eng) Mots-clés : Autism-spectrum-disorders paternal-age autistic-traits behavioral-genetics Index. décimale : PER Périodiques Résumé : Background: Despite extensive efforts, the causes of autism remain unknown. Advancing paternal age has been associated with various neurodevelopmental disorders. We aim to investigate three unresolved questions: (a) What is the association between paternal age and autism spectrum disorders (ASD)?; (b) Does paternal age moderate the genetic and environmental etiological factors for ASD? (c) Does paternal age affect normal variation in autistic-like traits?
Methods: Two nationally representative twin studies from Sweden (n = 11, 122, assessed at age 9 or 12) and the UK (n = 13, 524, assessed at age 9) were used. Categorical and continuous measures of ASD, autistic-like traits and autistic similarity were calculated and compared over paternal age categories.
Results: Both cohorts showed a strong association between paternal age and the risk for ASD. A U-shaped risk association could be discerned since the offspring of both the youngest and oldest fathers showed an elevation in the risk for ASD. Autistic similarity increased with advancing paternal age in both monozygotic and dizygotic twins. Both cohorts showed significantly higher autistic-like traits in the offspring of the youngest and oldest fathers.
Conclusions: Phenomena associated with paternal age are clearly involved in the trajectories leading to autistic-like traits and ASD. Mechanisms influencing the trajectories might differ between older and younger fathers. Molecular genetic studies are now needed in order to further understand the association between paternal age and ASD, as well as normal variation in social, language, and repetitive behaviors in the general population.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2010.02223.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=102

Titre : Using DNA to predict behaviour problems from preschool to adulthood Type de document : Texte imprimé et/ou numérique Auteurs : Agnieszka GIDZIELA, Auteur ; Kaili RIMFELD, Auteur ; Margherita MALANCHINI, Auteur ; Andrea G. ALLEGRINI, Auteur ; Andrew MCMILLAN, Auteur ; Saskia SELZAM, Auteur ; Angelica RONALD, Auteur ; Essi VIDING, Auteur ; Sophie VON STUMM, Auteur ; Thalia C.

We tested here if the prediction of behaviour problems from genome-wide polygenic scores (GPS) can be improved by creating composites across ages and across raters and by using a multi-GPS approach that includes GPS for adult psychiatric disorders as well as for childhood behaviour problems. METHOD: Our sample included 3,065 genotyped unrelated individuals from the Twins Early Development Study who were assessed longitudinally for hyperactivity, conduct, emotional problems, and peer problems as rated by parents, teachers, and children themselves. GPS created from 15 genome-wide association studies were used separately and jointly to test the prediction of behaviour problems composites (general behaviour problems, externalising, and internalising) across ages (from age 2 to 21) and across raters in penalised regression models. Based on the regression weights, we created multi-trait GPS reflecting the best prediction of behaviour problems. We compared GPS prediction to twin heritability using the same sample and measures. RESULTS: Multi-GPS prediction of behaviour problems increased from <2% of the variance for observed traits to up to 6% for cross-age and cross-rater composites. Twin study estimates of heritability, although to a lesser extent, mirrored patterns of multi-GPS prediction as they increased from <40% to 83%. CONCLUSIONS: The ability of GPS to predict behaviour problems can be improved by using multiple GPS, cross-age composites and cross-rater composites, although the effect sizes remain modest, up to 6%. Our approach can be used in any genotyped sample to create multi-trait GPS predictors of behaviour problems that will be more predictive than polygenic scores based on a single age, rater, or GPS.

Titre : Who is afraid of math?

PETRILL, Auteur Article en page(s) : p.1056-1064 Langues : Anglais (eng) Mots-clés : Mathematical anxiety general anxiety math cognition quantitative genetics Index. décimale : PER Périodiques Résumé : Background Emerging work suggests that academic achievement may be influenced by the management of affect as well as through efficient information processing of task demands. In particular, mathematical anxiety has attracted recent attention because of its damaging psychological effects and potential associations with mathematical problem solving and achievement. This study investigated the genetic and environmental factors contributing to the observed differences in the anxiety people feel when confronted with mathematical tasks. In addition, the genetic and environmental mechanisms that link mathematical anxiety with math cognition and general anxiety were also explored. Methods Univariate and multivariate quantitative genetic models were conducted in a sample of 514 12-year-old twin siblings. Results Genetic factors accounted for roughly 40% of the variation in mathematical anxiety, with the remaining being accounted for by child-specific environmental factors. Multivariate genetic analyses suggested that mathematical anxiety was influenced by the genetic and nonfamilial environmental risk factors associated with general anxiety and additional independent genetic influences associated with math-based problem solving. Conclusions The development of mathematical anxiety may involve not only exposure to negative experiences with mathematics, but also likely involves genetic risks related to both anxiety and math cognition. These results suggest that integrating cognitive and affective domains may be particularly important for mathematics and may extend to other areas of academic achievement.
