We identified three variants in two genes associated with Coffin–Siris syndrome (SMARCA4, SOX4), two variants in ADNP (Helsmoortel van der Aa syndrome), one variant in SMARCA2 (Nicolaides–Baraitser syndrome), and one variant in ACTL6B (Intellectual developmental disorder), all of which are associated with BAF (SWI/SNF) complex [35,36]. Here, SOX4 is linked to ADNP-related multiple congenital anomalies-intellectual disability-autism spectrum disorder.
