Dev Med Child Neurol. 1992 Nov;34(11):1005-9. doi: 10.1111/j.1469-8749.1992.tb11406.x.

Abstract

The authors report the case of a 2 1/2-year-old male with autism, with an 18q- chromosomal abnormality in the absence of phenotypical features of the 18q- syndrome. It is suggested that clinicians evaluating children with autistic disorders consider obtaining chromosome analysis, even in the absence of phenotypical abnormalities.
