Contribution of families using the GenIDA database to the description of MED13L syndrome and literature review / Roseline CAUMES in Journal of Neurodevelopmental Disorders, 17 (2025)  

Public ISBD [article]  inJournal of Neurodevelopmental Disorders > 17 (2025) Titre : Contribution of families using the GenIDA database to the description of MED13L syndrome and literature review Type de document : texte imprimé Auteurs : Roseline CAUMES, Auteur ; Pauline BURGER, Auteur ; Jean-Louis MANDEL, Auteur ; Hélène BÉHAL, Auteur ; Jamal GHOUMID, Auteur ; Thomas SMOL, Auteur Langues : Anglais (eng) Mots-clés : Humans  Intellectual Disability/genetics/epidemiology/physiopathology  Male  Female  Child  Developmental Disabilities/genetics  Mediator Complex/genetics  Child, Preschool  Phenotype  Adolescent  Databases, Factual  Family  Infant  Intellectual disability  Med13l  Patient registry  collected and informed consent was obtained for genetic studies. Analyses were  performed on a diagnostic basis in accordance with the bioethical rules of French  law. Competing interests: The authors declare no competing interests. Index. décimale : PER Périodiques Résumé : The GenIDA project aims to improve the understanding and management of rare genetic forms of intellectual disability by fostering collaboration among patients, caregivers, healthcare professionals, and research professionals. Clinical data is provided by patients' families via a structured questionnaire to identify medically relevant insights and better understand the natural history of rare diseases. This study focused on MED13L syndrome, analyzing data from 41 patients in the GenIDA database and comparing it with 102 cases from the scientific literature and 6 new descriptions of patients from our medical center.The GenIDA series confirmed the key features of MED13L syndrome, including global developmental delay, poor speech, intellectual disability, and cardiac defects (OMIM #616789), at frequencies similar to those reported in the literature. The GenIDA series identified a higher prevalence of visual impairment (76%) and highlighted under-recognized musculoskeletal issues, such as foot deformities, which had previously received little attention. This study highlights the value of family-reported data in describing the full phenotype of rare syndromes. A comprehensive review of published cases showed that patients with missense variants have more severe impairments, including increased cardiac defects, global developmental delay, and a higher incidence of epilepsy, than patients with premature truncated variants.These findings highlight the importance of family involvement in rare disease research and the need for further studies to explore genotype-phenotype correlations to improve patient care and outcomes.

Methods: A sample of 2,796 female adolescent twins ascertained from birth records provided Junior Eysenck Personality Questionnaire data. The average age of the sample was 17.0 years (S.D. 2.3). Genetic analyses of continuous and extreme personality scores were conducted. Results were compared for 3,178 adult female twins. Results: Genetic analysis of continuous traits in adolescent female twins were similar to findings in adult female twins, with genetic influences accounting for between 37% and 44% of the variance in Extraversion (Ex), Neuroticism (N), and Social Non-Conformity (SNC), with significant evidence of shared environmental influences (19%) found only for SNC in the adult female twins. Analyses of extreme personality characteristics, defined categorically, in the adolescent data and replicated in the adult female data, yielded estimates for high N and high SNC that deviated substantially (p < .05) from those obtained in the continuous trait analyses, and provided suggestive evidence that shared family environment may play a more important role in determining personality deviance than has been previously found when personality is viewed continuously. However, multiple-threshold models that assumed the same genetic and environmental determinants of both normative range variation and extreme scores gave acceptable fits for each personality dimension. Conclusions: The hypothesis of differences in genetic or environmental factors responsible for N and SNC among female twins with scores in the extreme versus normative ranges was partially supported, but not for Ex.

Genetic Variation in Melatonin Pathway Enzymes in Children with Autism Spectrum Disorder and Comorbid Sleep Onset Delay / Olivia J. VEATCH in Journal of Autism and Developmental Disorders, 45-1 (January 2015)

Genes whose products regulate endogenous melatonin modify sleep patterns and have been implicated in ASD. Genetic factors likely contribute to comorbid expression of sleep disorders in ASD. We studied a clinically unique ASD subgroup, consisting solely of children with comorbid expression of sleep onset delay. We evaluated variation in two melatonin pathway genes, acetylserotonin O-methyltransferase (ASMT) and cytochrome P450 1A2 (CYP1A2). We observed higher frequencies than currently reported (p < 0.04) for variants evidenced to decrease ASMT expression and related to decreased CYP1A2 enzyme activity (p ≤ 0.0007). We detected a relationship between genotypes in ASMT and CYP1A2 (r2 = 0.63). Our results indicate that expression of sleep onset delay relates to melatonin pathway genes.

Individuals with 22q11.2DS have elevated rates of community diagnoses of autism spectrum disorder (ASD), schizophrenia, and a range of medical problems and birth defects that necessitate extensive medical screening. Case reports of 22q11.2DupS include patients with ASD, fewer medical problems, and no schizophrenia; however, no prospective cohort study has been reported. The goals of the study were to (1) characterize the neuropsychiatric functioning of a cohort of individuals with 22q11.2DupS in comparison to large samples of typically developing controls (TDCs), ASD and 22q11.2DS; (2) estimate the prevalence of ASD in 22q11.2DupS; (3) determine whether the indications that prompted the genetic testing in 22q11.2DupS differ from 22q11.2DS and (4) determine whether comprehensive medical screening should be recommended for those diagnosed with 22q11.2DupS. METHODS: Medical characterization was done by parental questionnaire and medical chart review of individuals with 22q11.2DupS (n = 37) and 22q11.2DS (n = 101). Neuropsychiatric characterization of children with 22.11.2DupS, 22q11.2DS, TDCs, and ASD was done by parent-report questionnaires; in addition, the ASD and 22q11.2DupS groups received the Autism Diagnostic Interview-Revised and Autism Diagnostic Observation Schedule. RESULTS: Individuals with 22q11.2DupS, 22q11.2DS, and ASD had significantly impaired social interaction and adaptive behavior skills compared to TDCs. Overall, 38% of children aged 2-18 with 22q11.2DupS had community diagnoses of ASD, but fewer (14-25%) met on the basis of best clinical judgment that included ADI-R and ADOS data. Indications for genetic testing were significantly different for 22q11.2DupS and 22q11.2DS, with the deletions more commonly tested because of birth defects or medical problems, and the duplications because of developmental delay. However, when the screening protocol for 22q11.2DS was applied to the 22q11.2DupS sample, several medical problems were identified that would pose significant risk if left undetected. CONCLUSIONS: 22q11.2DupS has a high rate of ASD at 14-25%, among the highest of any genetic disorder. Prospective medical screening should be done for all patients with 22q11.2DupS, including those diagnosed due to developmental delays and ASD alone.

5-HTTLPR moderates the effect of relational peer victimization on depressive symptoms in adolescent girls / Corina BENJET in Journal of Child Psychology and Psychiatry, 51-2 (February 2010)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 51-2 (February 2010) . - p.173-179 Titre : 5-HTTLPR moderates the effect of relational peer victimization on depressive symptoms in adolescent girls Type de document : texte imprimé Auteurs : Corina BENJET, Auteur ; Renee THOMPSON, Auteur ; Ian H. GOTLIB, Auteur Année de publication : 2010 Article en page(s) : p.173-179 Langues : Anglais (eng) Mots-clés : Peer-victimization bullying depression genetic-polymorphisms 5-HTTLPR Index. décimale : PER Périodiques Résumé : Background: Relational peer victimization is associated with internalizing symptoms. Compared to boys, girls are more likely to be both relationally victimized by peers and distressed by the victimization. While previous studies have reported that a functional polymorphism in the promoter region of the serotonin transporter gene (5-HTTLPR) moderates the effect of stressful life events on depressive symptoms, the present study is the first to evaluate the interaction of this polymorphism with relational peer victimization to predict level of depressive symptoms in young girls. Methods: Participants were 78 girls ages 10 to 14 who had no current or past Axis I disorder. Girls were genotyped for 5-HTTLPR; peer victimization was assessed with the Social Experiences Questionnaire, and depressive symptoms with the Children's Depression Inventory. Results: The 5-HTTLPR polymorphism alone did not predict level of depressive symptoms; the interaction of 5-HTTLPR and relational peer victimization, however, was a significant predictor of depressive symptoms. Follow-up analyses indicated that peer victimization significantly predicted level of depressive symptoms only for girls who were homozygous for the short allele, and not for girls homozygous for the long allele or who were heterozygous for the short and long alleles. Conclusions: The findings support the diathesis-stress model of depression: having two 5-HTTLPR short alleles confers vulnerability to depressive symptoms in adolescent girls when they experience relational peer victimization. These findings also suggest that relational peer victimization, at least for girls with genetic vulnerability, is a significant source of stress and should be recognized in the monitoring and prevention of bullying.
