The c.101A>G (p.N34S) alteration is located in exon 1 (coding exon 1) of the IFNA17 gene. This alteration results from a A to G substitution at nucleotide position 101, causing the asparagine (N) at amino acid position 34 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
