There were 51 CON subjects misclassified as AE/Non-FAS. In comparison to the CON subjects that were correctly classified (n = 134), these subjects differed significantly on age (younger), FSIQ (lower), country (more from South Africa than U.S.), race (fewer White subjects), ethnicity (fewer Hispanic subjects), microcephaly (more likely), and smooth philtrum (more likely). They were marginally different on growth deficiency (more likely; Fisher’s exact p = .079) and weight (more likely to be ≤10th percentile; Fisher’s exact p = .062). They were not different on sex, handedness, height, structural abnormality, short palpebral fissures, or thin vermillion. They differed significantly on all of the neuropsychological variables (misclassified < correctly classified).
