DNASE1L3 Gene

What is the DNASE1L3 gene?

DNASE1L3 encodes deoxyribonuclease 1 like 3, a protein involved in nucleic acid sensing. It belongs to the Innate Immunity category and is part of the Innate Immunity & Interferons biological cluster. DNASE1L3 degrades extracellular chromatin released from dying cells, particularly neutrophil extracellular traps (NETs). Deficiency causes lupus-like disease due to accumulation of immunogenic DNA complexes.

Biological role and pathway

DNASE1L3 is involved in the nucleic acid sensing 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 DNASE1L3 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.

• rs35677470— DNASE1L3 variant
• rs1005753— DNASE1L3 variant
• rs3757247— DNASE1L3 variant

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 DNASE1L3 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.
