AVP Gene

What is the AVP gene?

AVP encodes arginine vasopressin (antidiuretic hormone), a protein involved in fluid balance / HPA axis modulation. It belongs to the Neuroendocrine category and is part of the Autonomic Nervous System biological cluster. AVP encodes arginine vasopressin (ADH), which regulates water reabsorption in the kidney and modulates the HPA axis stress response.

Biological role and pathway

AVP is involved in the fluid balance / HPA axis modulation pathway, which plays a central role in regulating physiological processes relevant to immune defence, cellular energy, and systemic homeostasis. Genes within the Autonomic Nervous System 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 AVP gene have been studied in relation to neuroendocrine and chronic illness. Each variant represents a single nucleotide position where individuals may carry different alleles.

• rs2282018— AVP variant
• rs3759129— AVP variant

Conditions studied in relation to AVP

Research into AVP variants has explored associations with the following conditions. These are areas of scientific investigation and do not imply that AVP 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 AVP and related genes in the autonomic nervous system 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.

AVP does not act in isolation. The following genes are functionally related and may be analysed together for a more complete picture of your genetic predispositions.
