Abstract

This study presents the first longitudinal analysis of early gesture development in FXS by using a multigroup design, clarifying the relative roles of cognitive deficits and ASD symptom severity in the development of gesture use in FXS. These findings offer novel evidence that early gesture use in FXS may reflect broader features of the FXS phenotype rather than predicting later social-communicative deficits characteristic of comorbid ASD.
