Genes affected

SYT6 (HGNC:18638): (synaptotagmin 6) The protein encoded by this gene belongs to the synaptotagmin family. Synaptotagmins share a common domain structure that includes a transmembrane domain and a cytoplasmic region composed of 2 C2 domains, and are involved in calcium-dependent exocytosis of synaptic vesicles. This protein has been shown to be a key component of the secretory machinery involved in acrosomal exocytosis. Alternatively spliced transcript variants have been found for this gene.

The c.797A>T (p.D266V) alteration is located in exon 3 (coding exon 2) of the SYT6 gene. This alteration results from a A to T substitution at nucleotide position 797, causing the aspartic acid (D) at amino acid position 266 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
