To address this critical gap in the literature, the current study examined the predictive validity of (1) demographics, (2) core autism symptoms, (3) cognitive abilities and adaptive behavior, (4) comorbid psychopathology, and (5) medical problems, for suicide-related behaviors among autistic youth (N?=?481; M(age)?=?11.56 years). As indices of suicide-related behaviors, parents reported on whether the child had ever (1) talked about killing themselves, and (2) engaged in deliberate self-harm or attempted suicide. These two suicide-related outcomes had distinct clinical correlates, including child age, parental education, restricted and repetitive behaviors, IQ and adaptive behavior, affective and conduct problems, and medical concerns.

A 1.5 Mb duplication was identified in one girl with severe expressive language deficits and anxiety among 1,142 ASD individuals screened for this duplication. Family-based association studies of Tag-SNPs in three genes (STX1A , CYLN2 and GTF2i) in two multiplex autism family cohorts revealed strong association of two GTF2i SNPs and their haplotype in Cohort 1 and the combined families. The risk alleles and haplotype were associated with severe problems in social interaction and excessive repetitive behaviors. Our findings suggest the GTF2i gene is important in the etiology of autism in individuals with this duplication and in non-duplication cases with severe social interaction problems and repetitive behaviors.

Behavioral Development and Sociodemographics of Infants and Young Children at Higher and Lower Risk for Autism Spectrum Disorders / Maurice A. FELDMAN in Journal of Autism and Developmental Disorders, 45-5 (May 2015)

This cross-sectional study used the Parent Observation of Early Markers Scale (POEMS, Feldman et al. in J Autism Dev Disord 42:13–12, 2012) to identify early signs of ASD in 69 ASD high-risk (older sibling diagnosed with ASD) and 69 sex and aged-matched ASD low-risk second-born or later infants (no family history of ASD) between 6 and 36 months of age. Family sociodemographic comparisons were also made between the risk groups. The high-risk children had significantly more elevated POEMS items than the low-risk children at 12, 18, 24, 30 and 36 months of age, even when the children subsequently diagnosed with ASD were removed from the analyses. Families of the high-risk group had older parents, lower family income and fewer mothers working out of the home than the low-risk group. These sociodemographic variables were not significantly correlated with POEMS scores. The results suggest that high-risk infants may show signs of the broader ASD phenotype as early as 12 months of age that may be unrelated to observed sociodemographic family differences.

Homozygosity for the 10-repeat dopamine transporter (DAT1) allele is associated with reduced EEG response in males with ASD / Calvin P. SJAARDA in Research in Autism Spectrum Disorders, 60 (April 2019)

Method This report explored the visual processing of individuals with ASD (n?=?50) compared with their first-degree relatives (n?=?117) using electroencephalogram (EEG), and associated EEG response with specific polymorphisms in the COMT, OXTR, SLC6A4 and DAT1 genes. Results Polymorphisms in the COMT and OXTR genes were not associated with any specific EEG response; on the other hand, the 5-HTTLPR polymorphism located upstream of SLC6A4 was associated with increased latency of the P1 component of the EEG response, and DAT1 genotype correlated with reduced amplitude of the N170 component in male participants with ASD. Conclusion These results suggest an interaction between DAT1 genotype and male participants with ASD characterized by reduced cognitive performance when processing faces as measured by EEG. Identifying ASD functional markers and grouping individuals with shared genetic biomarkers or endophenotypes may facilitate greater understanding of the heterogeneity underlying ASD leading to improved diagnosis and treatment of ASD.

Maternal serotonin transporter genotype affects risk for ASD with exposure to prenatal stress / Patrick M. HECHT in Autism Research, 9-11 (November 2016)

HECHT, Auteur ; Melissa HUDSON, Auteur ; Susan L. CONNORS, Auteur ; Michael R. TILLEY, Auteur ; Xudong LIU, Auteur ; David Q. BEVERSDORF, Auteur Article en page(s) : p.1151-1160 Langues : Anglais (eng) Mots-clés : autism spectrum disorders  serotonin  stress  prenatal stress  development  environmental influences Index. décimale : PER Périodiques Résumé : Stress exposure during gestation is implicated in several neuropsychiatric conditions, including autism spectrum disorder (ASD). Previous research showed that prenatal stress increases risk for ASD with peak exposure during the end of the second and the beginning of the third trimester. However, exposures to prenatal stress do not always result in ASD, suggesting that other factors may interact with environmental stressors to increase ASD risk. The present study examined a maternal genetic variation in the promoter region of the serotonin transporter gene (5-HTTLPR) affecting stress tolerance and its interaction with the effect of environmental stressors on risk for ASD. Two independent cohorts of mothers of ASD children recruited by the University of Missouri and Queen's University were surveyed regarding the prenatal environment and genotyping on 5-HTTLPR was performed to explore this relationship. In both samples, mothers of children with ASD carrying the stress susceptible short allele variant of 5-HTTLPR experienced a greater number of stressors and greater stress severity when compared to mothers carrying the long allele variant. The temporal peak of stressors during gestation in these mothers was consistent with previous findings. Additionally, increased exposure to prenatal stress was not reported in the pregnancies of typically developing siblings from the same mothers, regardless of maternal genotype, suggesting against the possibility that the short allele might increase the recall of stress during pregnancy. The present study provides further evidence of a specific maternal polymorphism that may affect the risk for ASD with exposure to prenatal stress.
