Ambry Genetics

Dec 01, 2022

The c.278G>T (p.G93V) alteration is located in exon 2 (coding exon 1) of the IFI44 gene. This alteration results from a G to T substitution at nucleotide position 278, causing the glycine (G) at amino acid position 93 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
