The c.1375G>A (p.G459R) alteration is located in exon 6 (coding exon 6) of the SYT10 gene. This alteration results from a G to A substitution at nucleotide position 1375, causing the glycine (G) at amino acid position 459 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
