What is the rs12944590 variant?
rs12944590 is a SNP (single nucleotide polymorphism) in the CCK (Cholecystokinin) gene. It belongs to the Neuroendocrine category and is part of the Neurological & Cognitive Function biological cluster. CCK encodes cholecystokinin, a gut hormone that promotes bile and enzyme secretion and signals satiety via vagal afferents.
Biological role and pathway
This variant sits within the CCK gene, which is involved in the gut-brain satiety / gallbladder pathway. 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 — particularly under conditions of physiological stress such as viral infection or prolonged illness.
rs12944590 and Long COVID / ME-CFS research
CCK-mediated vagal signaling is part of gut-brain communication; variants may affect satiety signaling and digestive function disrupted in Long COVID GI symptoms.

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 CCK and the rs12944590 variant.
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.
Frequently asked questions
What is the rs12944590 variant in the CCK gene?
rs12944590 is a single nucleotide polymorphism (SNP) located in the CCK (Cholecystokinin) gene, which is involved in gut-brain satiety / gallbladder. CCK encodes cholecystokinin, a gut hormone that promotes bile and enzyme secretion and signals satiety via vagal afferents.
How may the rs12944590 variant relate to Long COVID or ME/CFS?
CCK-mediated vagal signaling is part of gut-brain communication; variants may affect satiety signaling and digestive function disrupted in Long COVID GI symptoms.
Can a consumer DNA test detect the rs12944590 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. This is not a diagnostic service — results are informational and educational only.
