Genes affected

(HGNC:):

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]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.78).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.557 is higher than 0.05.
