title: 18q- chromosomal abnormality in a phenotypically normal 2 1/2-year-old male with autism.
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.
