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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 07, 2022The c.118C>G (p.L40V) alteration is located in exon 1 (coding exon 1) of the IFNW1 gene. This alteration results from a C to G substitution at nucleotide position 118, causing the leucine (L) at amino acid position 40 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
