SYTL4 and autism: As presented in Table 2 [26], extensive biological processes of the SYTL4 gene pertain to synaptic vesicle functions, including neurotransmitter secretion and regulation of signaling, RAB protein signal transduction, glutamate secretion, neuro-muscular synaptic transmission, and axonogenesis, all of which are relevant for proper neuronal function, and thus important in autism.
