WebAt neuronal synapses, synaptotagmin-1 (syt1) acts as a Ca 2+ sensor that synchronizes neurotransmitter release with Ca 2+ influx during action potential firing. Heterozygous missense mutations in syt1 have recently been associated with a severe but heterogeneous developmental syndrome, termed syt1-associated neurodevelopmental disorder. WebFIGURE 3 Overview of the pathogenic Stx1b and Syt1 variants’ effects on synaptic vesicle release. (A) Summary of all reported pathogenic Stx1b (NCBI Accession #: NP_443106.1) variants and the most common clinical phenotype of the patients harboring these variants (Variants are color-coded based on their effects on the protein. Nonsense mutations are …
