FN1 and autism: T3/ASD genes involved in cytoskeleton organization and cell migration (Table 2) are GNAS that codes for G-protein α subunit (Gs-α) (329); FN1 that codes for fibronectin, an extracellular matrix protein involved in cell adhesion and migration, found increased in serum of children with autism (330); SERPINH1 that codes for heat shock protein 47 that binds collagen and was found abnormally expressed in the temporal cortex of ASD patients (331); and NEFH, NEFM, and NEFL code for neurofilament subunits and has been found altered in the frontal cortex neurons in children with autism (332).
