It would also be of great interest to conduct similar studies for other members of the Contactin Associated Protein family, which have also been associated with neurodevelopmental disorders such as ASD, especially Caspr3/CNTNAP3 (Vaags et al., 2012; Turner et al., 2017), Caspr4/CNTNAP4 (Wang et al., 2010; O’Roak et al., 2012; Costa et al., 2022), and Caspr5/CNTNAP5 (Pagnamenta et al., 2010; Aleo et al., 2020; Ludington et al., 2020). This evidence concerns the gene CNTNAP4 and neurodevelopmental disorder.
