Little effort has been made to characterize the developmental anatomic phenotype of autism; although there is evidence of an increased head circumference and brain size, few other physical characteristics have been studied. The head circumference, body length/height, and weight measurements of infants, who were later diagnosed with high-functioning autism (HFA, n = 16) and Asperger disorder (AsD, n = 12), were extracted from health records over the first 3 years of life and compared to the measurements of a matched normal control group (n = 19). Using linear mixed-effects models, no differences were found in the average growth rate for head circumference, stature, or weight between the child..
