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.410C>A (p.A137D) alteration is located in exon 3 (coding exon 2) of the SYT6 gene. This alteration results from a C to A substitution at nucleotide position 410, causing the alanine (A) at amino acid position 137 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
