SLC5A7 Gene

What is the SLC5A7 gene?

SLC5A7 encodes solute carrier family 5 member 7 (high-affinity choline transporter), a protein involved in choline uptake for ACh synthesis. It belongs to the Neurotransmitter category and is part of the Autonomic Nervous System biological cluster. SLC5A7 encodes the high-affinity choline transporter (CHT1), which limits ACh synthesis by controlling choline uptake into cholinergic neurons.

Biological role and pathway

SLC5A7 is involved in the choline uptake for ACh synthesis 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 SLC5A7 gene have been studied in relation to neurotransmitter and chronic illness. Each variant represents a single nucleotide position where individuals may carry different alleles.

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 SLC5A7 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.
