Fourteen subjects (approximately 25% of the same) scored above the cutoff for autism, suggesting a relatively high incidence of autistic behaviour. All but 2 of these 14 were in the mildly or moderately autistic range. However, and only a few items received severe ratings suggesting that severe autism is relatively rare in fraX, at least during the early years. The CARS resulted in continuum of autistic ratings in the fraX population , but no particular items on the CARS contributed of autistic ratings in the fraX population, but no particular items on the CARS contributed disproportionately to autism ratings. A visual comparison of ratings in an autistic non-fraX sample revealed similar profiles of ratings suggesting that differentiating fraX and autism on the basis of CARS ratings is not likely. Within the fraX group chronological age and socioecomomic status did not correlated with CARS ratings, but severity of delay was strongly related such that more severely delayed children scored higher (more autistic) on the CARS.
