The c.482G>C (p.G161A) alteration is located in exon 4 (coding exon 4) of the NEMP2 gene. This alteration results from a G to C substitution at nucleotide position 482, causing the glycine (G) at amino acid position 161 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
