LGP2 Gene

What is the LGP2 gene?

LGP2 encodes laboratory of genetics and physiology 2, a protein involved in RLR signaling. It belongs to the Innate Immunity category and is part of the Innate Immunity & Interferons biological cluster. LGP2 (DHX58) is a DExH RNA helicase related to RIG-I and MDA5. It lacks signaling CARDs but regulates RNA sensing by facilitating MDA5 filament assembly and modulating RIG-I signaling amplitude.

Biological role and pathway

LGP2 is involved in the RLR signaling pathway, which plays a central role in regulating physiological processes relevant to immune defence, cellular energy, and systemic homeostasis. Genes within the Innate Immunity & Interferons 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 LGP2 gene have been studied in relation to innate immunity and chronic illness. Each variant represents a single nucleotide position where individuals may carry different alleles.

• rs10272618— LGP2 variant
• rs11875065— LGP2 variant

Conditions studied in relation to LGP2

Research into LGP2 variants has explored associations with the following conditions. These are areas of scientific investigation and do not imply that LGP2 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 LGP2 and related genes in the innate immunity & interferons 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.
