Genes affected

IFNW1 (HGNC:5448): (interferon omega 1) The protein encoded by this gene is an interferon and possesses antiviral activity. The encoded protein binds to the interferon alpha/beta receptor but not to the interferon gamma receptor. This intronless gene has several pseudogenes spread throughout the genome.

Ambry Genetics

May 18, 2022

The c.485G>A (p.C162Y) alteration is located in exon 1 (coding exon 1) of the IFNW1 gene. This alteration results from a G to A substitution at nucleotide position 485, causing the cysteine (C) at amino acid position 162 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
