The c.3245G>A (p.S1082N) alteration is located in exon 12 (coding exon 12) of the NRDE2 gene. This alteration results from a G to A substitution at nucleotide position 3245, causing the serine (S) at amino acid position 1082 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
