The c.482G>A (p.S161N) alteration is located in exon 1 (coding exon 1) of the IFNA13 gene. This alteration results from a G to A substitution at nucleotide position 482, causing the serine (S) at amino acid position 161 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
