Angkustsiri, Kathleen; Krakowiak, Paula; Moghaddam, Billur; Wardinsky, Terrance; Gardner, Jerald; Kalamkarian, Nareg; Hertz-Picciotto, Irva; Hansen, Robin L. – Autism: The International Journal of Research and Practice, 2011
Objective: There is clinical heterogeneity among the autism spectrum disorders (ASD). The presence of dysmorphology (minor physical anomalies; MPAs) is one possible tool for defining a clinically relevant subset in ASD. This study employs an adaptation of Miles and Hillman's (2000) classifications by using photographs to identify a subgroup with…

Macedoni-Luksic, Marta; Greiss-Hess, Laura; Rogers, Sally J.; Gosar, David; Lemons-Chitwood, Kerrie; Hagerman, Randi – Autism: The International Journal of Research and Practice, 2009
To address the specific impairment of imitation in autism, the imitation abilities of 22 children with fragile X syndrome (FXS) with and without autism were compared. Based on previous research, we predicted that children with FXS and autism would have significantly more difficulty with non-meaningful imitation tasks. After controlling for…

Milner, Katja M.; Craig, Ellen E.; Thompson, Russell J.; Veltman, Marijcke W. M.; Simon Thomas, N.; Roberts, Sian; Bellamy, Margaret; Curran, Sarah R.; Sporikou, Caroline M. J.; Bolton, Patrick F. – Journal of Child Psychology and Psychiatry, 2005
Background: Studies of chromosome 15 abnormality have implicated over-expression of paternally imprinted genes in the 15q11-13 region in the aetiology of autism. To test this hypothesis we compared individuals with Prader-Willi syndrome (PWS) due to uniparental disomy (UPD--where paternally imprinted genes are over-expressed) to individuals with…
