IFNA8
protein-codinginterferon alpha 8, the group of Interferons
Gene summary
Predicted to enable cytokine activity and type I interferon receptor binding activity. Predicted to be involved in several processes, including lymphocyte activation involved in immune response; response to exogenous dsRNA; and type I interferon-mediated signaling pathway. Predicted to act upstream of or within defense response to virus. Predicted to be located in extracellular region. Predicted to be active in obsolete extracellular space.

ClinVar Variants & Pathogenicity by Type
Statistics based on transcript NM_002170.4. Only rare variants are included.
We include only reliable ClinVar variants with their consequences to MANE Select, MANE Plus Clinical transcripts, or transcripts with TSL equal to 1. Click a count to filter the variants table below.
Slight differences between displayed counts and ClinVar may occur due to a different transcript/consequence chosen by our variant effect predictor, or because we classify Benign/Likely benign as Likely benign and Pathogenic/Likely pathogenic as Likely pathogenic.
