Description

The c.266A>G (p.N89S) alteration is located in exon 1 (coding exon 1) of the IFNA4 gene. This alteration results from a A to G substitution at nucleotide position 266, causing the asparagine (N) at amino acid position 89 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
