The c.463C>G (p.P155A) alteration is located in exon 4 (coding exon 4) of the NIPSNAP3B gene. This alteration results from a C to G substitution at nucleotide position 463, causing the proline (P) at amino acid position 155 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
