Genes affected

SYT13 (HGNC:14962): (synaptotagmin 13) This gene encodes a member of the large synaptotagmin protein family. Family members have an extracellular N-terminal transmembrane domain and a cytoplasmic C terminus with two tandem C2 domains (C2A and C2B). Synaptotogmin family members can form homo- and heteromeric complexes with each other. They also have different biochemical properties and developmental profiles, and patterns of tissue distribution. Synaptotagmins function as membrane traffickers in multicellular organisms. Two alternatively spliced transcript variants that encode different protein isoforms have been described for this gene.

The c.1210C>T (p.R404C) alteration is located in exon 6 (coding exon 6) of the SYT13 gene. This alteration results from a C to T substitution at nucleotide position 1210, causing the arginine (R) at amino acid position 404 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
