rs6277
Variant in the DRD2 gene (Dopamine Receptor D2)
rs6277 is a single nucleotide polymorphism (SNP) in the DRD2 gene, involved in dopaminergic signaling. Variants at this position have been studied in relation to immune function, metabolism, and chronic illness.

What is the rs6277 variant?
rs6277 is a SNP (single nucleotide polymorphism) in the DRD2 (Dopamine Receptor D2) gene. It belongs to the Neurotransmitter category and is part of the Neurological & Cognitive Function biological cluster. DRD2 encodes the D2 dopamine receptor, central to reward, cognition, movement, and modulation of immune function.
Biological role and pathway
This variant sits within the DRD2 gene, which is involved in the dopaminergic signaling 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.
rs6277 and Long COVID / ME-CFS research
DRD2 variants may influence dopaminergic tone and contribute to cognitive dysfunction, fatigue, and motivational deficits in Long COVID.

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 DRD2 and the rs6277 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.
Other variants in the DRD2 gene
The following variants in DRD2 are also studied in relation to chronic illness and may be analysed together for a more complete picture.
Frequently asked questions
What is the rs6277 variant in the DRD2 gene?
rs6277 is a single nucleotide polymorphism (SNP) located in the DRD2 (Dopamine Receptor D2) gene, which is involved in dopaminergic signaling. DRD2 encodes the D2 dopamine receptor, central to reward, cognition, movement, and modulation of immune function.
How may the rs6277 variant relate to Long COVID or ME/CFS?
DRD2 variants may influence dopaminergic tone and contribute to cognitive dysfunction, fatigue, and motivational deficits in Long COVID.
Can a consumer DNA test detect the rs6277 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.
