NF1 and RASopathy: Unimodal distribution and positive shift of ASD traits in NF1, CS, NS, and CFC suggest that all pathogenic variants related to RASopathies increase ASD traits (Adviento et al., 2014; Constantino et al., 2015; Morris et al., 2016; Payne et al., 2020)Intraclass correlations between NF1 first‐degree relatives suggest mutation specificity for the amount of ASD traits (Constantino et al., 2015; Morris et al., 2016)Higher ASD traits in NF1 with microdeletions (Kehrer‐Sawatzki et al., 2020)
