Mutations or deletions in genes encoding exocyst proteins, including EXOC2, EXOC4, EXOC7, and EXOC8, have been associated with ciliopathies and neural developmental disorders (Coulter et al., 2020; Dixon-Salazar et al., 2012; Shaheen et al., 2013; Turkyilmaz et al., 2021; Van Bergen et al., 2020). This evidence concerns the gene EXOC8 and ciliopathy.
