SYT1, which functions as calcium sensors in vesicular trafficking and exocytosis of neurotransmitters and hormones, is involved in the regulation of neurite outgrowth [35,36,37] and it is linked to a rare neurodevelopmental disorder known as SYT1-associated neurodevelopmental disorder or Baker-Gordon syndrome [38]. The gene discussed is SYT1; the disease is infantile hypotonia-oculomotor anomalies-hyperkinetic movements-developmental delay syndrome.
