  • Mutations of the X-linked genes encoding neuroligins NLGN3 and NLGN4 are associated with autism

    • Many studies have supported a genetic etiology for autism. Here we report mutations in two X-linked genes encoding neuroligins NLGN3 and NLGN4 in siblings with autism-spectrum disorders. These mutations affect cell-adhesion molecules localized at the synapse and suggest that a defect of synaptogenesis may predispose to autism.

  • Personality disorders in a total population twin cohort with eating disorders.
  • 2004
  • Ingår i: Comprehensive Psychiatry. - : Elsevier BV. - 0010-440X. ; 45:4, s. 261-267
  • Tidskriftsartikel (refereegranskat)abstract
    • Findings regarding the occurrence of personality disorders (PDs) in eating disorders (EDs) have been contradictory. Most previous studies have been clinic-based. The aims of the current study were to assess the prevalence of PD in ED in a population-based twin group and to establish the distribution of PD in three subgroups of ED. A two-step screening and diagnostic study of ED was performed in a large Danish twin population. Axis I and axis II DSM-III-R and DSM-IV ED diagnoses were made on the basis of results obtained at clinical investigations and interviews. Forty-nine percent of the participants with ED had at least one PD, compared to 26% in those with no ED (P <.001). Cluster C PD was the most common type of PD in all subgroups of ED, and cluster B PD was found only in participants with bulimic symptoms. Genetic factors appeared to contribute significantly to the variance of cluster C PD in ED, which was evaluated as a possibly important background factor in ED.

  • Interhemispheric transfer in high-functioning children and adolescents with autism spectrum disorders: a controlled pilot study.
  • 2004
  • Ingår i: Developmental medicine and child neurology. - 0012-1622. ; 46:7, s. 448-54
  • Tidskriftsartikel (refereegranskat)abstract
    • Autism is a neurodevelopmental disorder with strong genetic influences. Clinical experience and limited empirical evidence support the view that autism may be associated with aberrant interhemispheric information transfer. This empirical controlled study examined whether, at neuropsychological testing, children with autism showed problems with interhemispheric information transfer. The study included auditory, visual, and motor measures covering information transfer within, as well as across, modalities. Thirty children (24 males, 6 females; mean age 12 years 8 months, SD 2 years 8 months; range 9 years 5 months to 17 years 5 months) without learning disability but with autism spectrum disorders were compared with 30 children from a mainstream school matched for age, sex, and IQ>75. Children with autism spectrum disorder performed significantly worse than the comparison group on most of the tests (p=0.02 for auditory perception and attention, p=0.005 for visual perception, p=0.0001 for motor control, p=0.04 for tactile perception). Results support the notion that aberrant interhemispheric transfer may be involved in the pathogenesis or clinical course of autism. The findings were not accounted for by lower IQ in the group with autism.
