Ambry Genetics

Oct 25, 2022

The c.107G>A (p.S36N) alteration is located in exon 2 (coding exon 1) of the IFI44L gene. This alteration results from a G to A substitution at nucleotide position 107, causing the serine (S) at amino acid position 36 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
