Ambry Genetics

Dec 19, 2023

The c.352G>A (p.D118N) alteration is located in exon 1 (coding exon 1) of the IFNA5 gene. This alteration results from a G to A substitution at nucleotide position 352, causing the aspartic acid (D) at amino acid position 118 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
