Further evidence for a parent-of-origin effect at the NOP9 locus on language-related phenotypes / K. A. PETTIGREW in Journal of Neurodevelopmental Disorders, 8-1 (December 2016)

Titre : Further evidence for a parent-of-origin effect at the NOP9 locus on language-related phenotypes Type de document : Texte imprimé et/ou numérique Auteurs : K. A. PETTIGREW, Auteur ; E. FRINTON, Auteur ; R. NUDEL, Auteur ; M. T. M. CHAN, Auteur ; P. THOMPSON, Auteur ; M. E. HAYIOU-THOMAS, Auteur ; J. B. TALCOTT, Auteur ; J. STEIN, Auteur ; A. P. MONACO, Auteur ; C. HULME, Auteur ; M. J. SNOWLING, Auteur ; D. F. NEWBURY, Auteur ; S. PARACCHINI, Auteur Article en page(s) : p.24 Langues : Anglais (eng) Mots-clés : Candidate gene Dyslexia Genetic association Language impairment Parent-of-origin Index. décimale : PER Périodiques Résumé : BACKGROUND: Specific language impairment (SLI) is a common neurodevelopmental disorder, observed in 5-10 % of children. Family and twin studies suggest a strong genetic component, but relatively few candidate genes have been reported to date. A recent genome-wide association study (GWAS) described the first statistically significant association specifically for a SLI cohort between a missense variant (rs4280164) in the NOP9 gene and language-related phenotypes under a parent-of-origin model. Replications of these findings are particularly challenging because the availability of parental DNA is required. METHODS: We used two independent family-based cohorts characterised with reading- and language-related traits: a longitudinal cohort (n = 106 informative families) including children with language and reading difficulties and a nuclear family cohort (n = 264 families) selected for dyslexia. RESULTS: We observed association with language-related measures when modelling for parent-of-origin effects at the NOP9 locus in both cohorts: minimum P = 0.001 for phonological awareness with a paternal effect in the first cohort and minimum P = 0.0004 for irregular word reading with a maternal effect in the second cohort. Allelic and parental trends were not consistent when compared to the original study. CONCLUSIONS: A parent-of-origin effect at this locus was detected in both cohorts, albeit with different trends. These findings contribute in interpreting the original GWAS report and support further investigations of the NOP9 locus and its role in language-related traits. A systematic evaluation of parent-of-origin effects in genetic association studies has the potential to reveal novel mechanisms underlying complex traits.

We catalogued 23,109 coding de novo mutations (DNMs) from 6511 patients with autism spectrum disorder (ASD), 4,293 undiagnosed developmental disorder (UDD), 933 epileptic encephalopathy (EE), 1022 intellectual disability (ID), 1094 schizophrenia (SCZ), and 3391 controls. We evaluated that putative functional DNMs contribute to 38.11%, 34.40%, 33.31%, 10.98% and 6.91% of patients with ID, EE, UDD, ASD and SCZ, respectively. Consistent with phenotype similarity and heterogeneity in different NPDs, they show different degree of genetic association. Cross-disorder analysis of DNMs prioritized 321 candidate genes (FDR?0.05) and showed that genes shared in more disorders were more likely to exhibited specific expression pattern, functional pathway, genetic convergence, and genetic intolerance.
