The c.284G>A (p.G95D) alteration is located in exon 2 (coding exon 1) of the SV2C gene. This alteration results from a G to A substitution at nucleotide position 284, causing the glycine (G) at amino acid position 95 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
