HANSEN, Auteur ; Paul ASHWOOD, Auteur ; Isaac N. PESSAH, Auteur ; Irva HERTZ-PICCIOTTO, Auteur ; Judy VAN DE WATER, Auteur Année de publication : 2012 Article en page(s) : p.1435-1445 Langues : Anglais (eng) Mots-clés : Autism  Maternal antibodies  Autoantibodies  Fetal brain  Immunologie Index. décimale : PER Périodiques Résumé : Autism spectrum disorders (ASDs) affect approximately 1 in 110 children in the United States. This report profiles fetal-brain reactive autoantibodies of a large cohort of mothers of children with autism and controls, yielding significant associations between the presence of IgG reactivity to fetal brain proteins at 37 and 73 kDa and a childhood diagnosis of full autism (p = 0.0005), which also correlated with lower expressive language scores (p = 0.005). Additionally, we report on reactivity to proteins at 39 and 73 kDa, which correlated with the broader diagnosis of ASD (p = 0.0007) and increased irritability on the Aberrant Behavioral Checklist (p = 0.05). This study provides evidence of multiple patterns of reactivity to fetal brain proteins by maternal antibodies associated with ASD and specific childhood behavioral outcomes.

Brief Report: Plasma Leptin Levels are Elevated in Autism: Association with Early Onset Phenotype? / Paul ASHWOOD in Journal of Autism and Developmental Disorders, 38-1 (January 2008)

We examined the hormone/cytokine leptin in 70 children diagnosed with autism (including 37 with regression) compared with 99 age-matched controls including 50 typically developing (TD) controls, 26 siblings without autism, and 23 children with developmental disabilities (DD). Children with autism had significantly higher plasma leptin levels compared with TD controls (p < .006). When further sub-classified into regression or early onset autism, children with early onset autism had significantly higher plasma leptin levels compared with children with regressive autism (p < .042), TD controls (p < .0015), and DD controls (p < .004). We demonstrated an increase in leptin levels in autism, a finding driven by the early onset group.

Identification of Expanded Alleles of the FMR1 Gene in the CHildhood Autism Risks from Genes and Environment (CHARGE) Study / Flora TASSONE in Journal of Autism and Developmental Disorders, 43-3 (March 2013)

Expansion of a CGG trinucleotide repeat (200 repeats) in the 5?UTR of the fragile X mental retardation gene, is the single most prevalent cause of cognitive disabilities. Several screening studies for FXS, among individuals with ID from different ethnic populations, have indicated that the prevalence of the syndrome varies between 0.5 and 16 %. Because the high co-morbidity with autism, we have conducted a screening study of the cohort from CHARGE, a large-scale, population-based, case control study. We have identified six subjects carrying an expanded allele, which emphasize the importance of screening for FXS in a population with intellectual disabilities and ASD.

MAOA, DBH, and SLC6A4 variants in CHARGE: a case–control study of autism spectrum disorders / Flora TASSONE in Autism Research, 4-4 (August 2011)  

Public ISBD [article]  inAutism Research > 4-4 (August 2011) . - p.250-261 Titre : MAOA, DBH, and SLC6A4 variants in CHARGE: a case–control study of autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Flora TASSONE, Auteur ; Lihong QI, Auteur ; Wenting ZHANG, Auteur ; David J. HANSEN, Auteur ; Isaac N. PESSAH, Auteur ; Irva HERTZ-PICCIOTTO, Auteur Année de publication : 2011 Article en page(s) : p.250-261 Langues : Anglais (eng) Mots-clés : ASD  polymorphisms  SLC6A4  MAOA  DBH Index. décimale : PER Périodiques Résumé : Genetic factors are established to contribute to the development of autism. We examined three loci, serotonin transporter (SLC6A4), dopamine β-hydroxylase (DBH), and the variable number of tandem repeat promoter of the monoamine oxidase A (MAOA) for association with autism in participants from the Childhood Autism Risks from Genetics and the Environment (CHARGE ) Study, the first large-scale population-based case–control investigation of both environmental and genetic contributions to autism risk. Among male children enrolled in the CHARGE study we tested associations between each of the three polymorphisms and autism (AU) (n = 119), or a combined group of autism and other autism spectrum disorders (AU+ASD, which includes an additional n = 53) as compared with typically developing controls (TD, n = 137). The case–control association analysis showed neither SLC6A4 nor DBH to be statistically significantly associated with AU or ASD. However, the male children carrying 4 tandem repeats in the promoter region of the MAOA gene showed a two-fold higher risk of AU (or AU+ASD) than those carrying allele 3, adjusted for confounders (OR = 2.02, 95% CI = 1.12, 3.65, P = 0.02 for AU vs. TD, and OR = 2.05, 95% CI = 1.19, 3.53, P = 0.01 for ASD vs. TD). In addition, children of mothers homozygous for the 4 tandem repeat allele showed at least a three-fold higher risk of AU (or AU+ASD) than those with mothers homozygous for allele 3 (OR = 3.07, 95% CI = 1.19, 7.91, P = 0.02 for AU vs. TD, and OR = 3.26, 95% CI = 1.35, 7.89, P = 0.009 for AU+ASD vs. TD). These results suggest a potential role of the functional MAOA promoter alleles in the male child, the mother, or both in ASD.
