Ambry Genetics

Feb 09, 2023

The c.584T>C (p.I195T) alteration is located in exon 4 (coding exon 3) of the IFI44 gene. This alteration results from a T to C substitution at nucleotide position 584, causing the isoleucine (I) at amino acid position 195 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
