In addition, the SYTL4 protein directly interacts with FGF4, STX1B, SNAP29, SNAP23, SNAP47, RAB3A, RAB27A, RAB27B, RAB8A, STX4, STX19, STX3, STX11, and STX2 whose numerous transcriptome-wide isoforms are known as autism genes (https://gene.sfari.org/database/human-gene/). Here, SYTL4 is linked to autism.
