What is the rs1880676 variant?

rs1880676 is a SNP (single nucleotide polymorphism) in the CHAT (Choline O-Acetyltransferase) gene. It belongs to the Neurotransmitter category and is part of the Autonomic Nervous System biological cluster. CHAT encodes choline acetyltransferase, the enzyme that synthesizes acetylcholine from acetyl-CoA and choline in cholinergic neurons.

Biological role and pathway

This variant sits within the CHAT gene, which is involved in the acetylcholine biosynthesis pathway. 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 — particularly under conditions of physiological stress such as viral infection or prolonged illness.

rs1880676 and Long COVID / ME-CFS research

ChAT activity determines ACh synthesis capacity; variants may affect cholinergic neurotransmission and the vagal anti-inflammatory pathway relevant to autonomic dysfunction in Long COVID.

Frequently asked questions

What is the rs1880676 variant in the CHAT gene?

rs1880676 is a single nucleotide polymorphism (SNP) located in the CHAT (Choline O-Acetyltransferase) gene, which is involved in acetylcholine biosynthesis. CHAT encodes choline acetyltransferase, the enzyme that synthesizes acetylcholine from acetyl-CoA and choline in cholinergic neurons.

How may the rs1880676 variant relate to Long COVID or ME/CFS?

ChAT activity determines ACh synthesis capacity; variants may affect cholinergic neurotransmission and the vagal anti-inflammatory pathway relevant to autonomic dysfunction in Long COVID.

Can a consumer DNA test detect the rs1880676 variant?

Many consumer DNA tests such as 23andMe, AncestryDNA, and MyHeritage genotype common SNPs. ChronicDNA analyses your raw DNA file and reports on variants studied in relation to chronic illness, immune function, and metabolism.
