Genes affected

IFIT5 (HGNC:13328): (interferon induced protein with tetratricopeptide repeats 5) Enables nucleic acid binding activity. Involved in defense response to virus; negative regulation of viral genome replication; and positive regulation of I-kappaB kinase/NF-kappaB signaling. Located in actin cytoskeleton; apical part of cell; and ruffle membrane. Colocalizes with IkappaB kinase complex. [provided by Alliance of Genome Resources, Apr 2022]

The c.434G>A (p.G145D) alteration is located in exon 2 (coding exon 2) of the IFIT5 gene. This alteration results from a G to A substitution at nucleotide position 434, causing the glycine (G) at amino acid position 145 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
