The c.485G>A (p.G162D) alteration is located in exon 4 (coding exon 4) of the NIPSNAP3A gene. This alteration results from a G to A substitution at nucleotide position 485, causing the glycine (G) at amino acid position 162 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
