IRGM Gene

What is the IRGM gene?

IRGM encodes immunity related gtpase m, a protein involved in xenophagy / intracellular pathogen clearance. It belongs to the Autophagy category and is part of the Viral Defense & Interferon Response biological cluster. IRGM encodes an immunity-related GTPase that promotes autophagy of intracellular pathogens (xenophagy).

Biological role and pathway

IRGM is involved in the xenophagy / intracellular pathogen clearance 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 IRGM gene have been studied in relation to autophagy and chronic illness. Each variant represents a single nucleotide position where individuals may carry different alleles.

• rs13361189— IRGM variant
• rs4958847— IRGM variant

Conditions studied in relation to IRGM

Research into IRGM variants has explored associations with the following conditions. These are areas of scientific investigation and do not imply that IRGM 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 IRGM 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.
