IFNAR1 Gene

What is the IFNAR1 gene?

IFNAR1 encodes interferon alpha and beta receptor subunit 1, a protein involved in type I interferon receptor signaling. It belongs to the Viral Defense category and is part of the Viral Defense & Interferon Response biological cluster. IFNAR1 encodes the alpha subunit of the type I interferon receptor complex, essential for signaling by all type I interferons.

Biological role and pathway

IFNAR1 is involved in the type I interferon receptor signaling pathway, which plays a central role in regulating physiological processes relevant to immune defence, cellular energy, and systemic homeostasis. Genes within the Viral Defense & Interferon Response cluster work together to maintain balanced function across interconnected biological systems.

Variants in genes within this pathway may influence an individual's predisposition to altered function in these systems — particularly under conditions of physiological stress such as viral infection or prolonged illness.

Known genetic variants

The following variants (SNPs) in the IFNAR1 gene have been studied in relation to viral defense and chronic illness. Each variant represents a single nucleotide position where individuals may carry different alleles.

• rs2257167— IFNAR1 variant
• rs17875752— IFNAR1 variant

Conditions studied in relation to IFNAR1

Research into IFNAR1 variants has explored associations with the following conditions. These are areas of scientific investigation and do not imply that IFNAR1 causes or treats any condition.

Genetic insights from DNA data

Consumer DNA files from 23andMe, AncestryDNA, and MyHeritage contain raw SNP data. When you upload your file to ChronicDNA, the analysis engine checks your genotype against a curated panel of 80+ genes selected for their relevance to Long COVID, ME/CFS, and connected biological pathways - some of which may include IFNAR1 and related genes in the viral defense & interferon response pathway.

The report is educational - it explains which variants you carry, what the research says about them, and how they fit into the biological pathways most relevant to chronic illness. Results are presented in plain English with appropriate scientific context, no medical jargon, no scare tactics. All results should be discussed with a qualified healthcare provider.
