The c.677G>C (p.S226T) alteration is located in exon 6 (coding exon 6) of the NIPSNAP3B gene. This alteration results from a G to C substitution at nucleotide position 677, causing the serine (S) at amino acid position 226 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
