Genes affected
IFITM3 (HGNC:5414): (interferon induced transmembrane protein 3) Interferon-induced transmembrane (IFITM) proteins are a family of interferon induced antiviral proteins. The family contains five members, including IFITM1, IFITM2 and IFITM3 and belong to the CD225 superfamily. The protein encoded by this gene restricts cellular entry by diverse viral pathogens, such as influenza A virus, Ebola virus and Sars-CoV-2. [provided by RefSeq, Nov 2021]

The c.277G>A (p.V93M) alteration is located in exon 2 (coding exon 2) of the IFITM3 gene. This alteration results from a G to A substitution at nucleotide position 277, causing the valine (V) at amino acid position 93 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
