Feb 12, 2024

The c.587T>C (p.V196A) alteration is located in exon 5 (coding exon 5) of the NIPSNAP3B gene. This alteration results from a T to C substitution at nucleotide position 587, causing the valine (V) at amino acid position 196 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
