Peculiarities in the gestural repertoire: An early marker for Rett syndrome?

► The emergence of first gestures in girls with RTT is not necessarily delayed. ► The repertoire of communicative gestures, however, is restricted. ► Although girls with RTT have difficulties in their verbal communicative domain, gestures do not constitute a compensatory mechanism. ► A limited repertoire of gestures and qualitative peculiarities in other speech-language domains might be characteristic for a severe neurodevelopmental disorder like RTT.
