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.

Functional Evaluation of Hidden Figures Object Analysis in Children with Autistic Disorder / Krisztina L. MALISZA in Journal of Autism and Developmental Disorders, 41-1 (January 2011)

Overall greater functional MRI activity was observed in the two control groups compared to children with AD. Laterality differences were also evident, with AD subjects preferentially showing activity in the right medial temporal region while controls tended to activate the left medial temporal cortex. Reduced fMRI activity was observed in the parietal, ventral-temporal and hippocampal regions in the AD group, suggesting differences in the way that children with AD process the HFT.
