SNAP25 Gene

What is the SNAP25 gene?

SNAP25 encodes synaptosomal-associated protein 25, a protein involved in vesicle fusion and neurotransmitter release. It belongs to the Neuroplasticity category and is part of the Neurological & Cognitive Function biological cluster. SNAP25 is a SNARE complex protein essential for synaptic vesicle exocytosis and neurotransmitter release at synapses.

Biological role and pathway

SNAP25 is involved in the vesicle fusion and neurotransmitter release pathway, which plays a central role in regulating physiological processes relevant to immune defence, cellular energy, and systemic homeostasis. Genes within the Neurological & Cognitive Function 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 SNAP25 gene have been studied in relation to neuroplasticity and chronic illness. Each variant represents a single nucleotide position where individuals may carry different alleles.

• rs3746544— SNAP25 variant
• rs363050— SNAP25 variant

Conditions studied in relation to SNAP25

Research into SNAP25 variants has explored associations with the following conditions. These are areas of scientific investigation and do not imply that SNAP25 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 SNAP25 and related genes in the neurological & cognitive function 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.
