The c.575G>A (p.G192E) alteration is located in exon 2 (coding exon 2) of the SYT3 gene. This alteration results from a G to A substitution at nucleotide position 575, causing the glycine (G) at amino acid position 192 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
