Results  Phenotypic differences in the presentation of childhood AD in minority groups may indicate etiologic heterogeneity or different thresholds for diagnosis. Knowing the true pattern in underlying risk over time is of great interest, because short-term increases in true disease risk would support a role for nonheritable mechanisms in ASD etiology. Weak evidence was found for changes in the genetic and environmental factors underlying ASD and autistic traits over time.
