rs6271
Variant in the DBH gene (Dopamine Beta-Hydroxylase)
rs6271 is a single nucleotide polymorphism (SNP) in the DBH gene, involved in norepinephrine biosynthesis. Variants at this position have been studied in relation to immune function, metabolism, and chronic illness.

What is the rs6271 variant?
rs6271 is a SNP (single nucleotide polymorphism) in the DBH (Dopamine Beta-Hydroxylase) gene. It belongs to the Neurotransmitter category and is part of the Autonomic Nervous System biological cluster. DBH encodes dopamine beta-hydroxylase, the enzyme that converts dopamine to norepinephrine in sympathetic neurons and adrenal chromaffin cells.
Biological role and pathway
This variant sits within the DBH gene, which is involved in the norepinephrine 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.
rs6271 and Long COVID / ME-CFS research
DBH variants affect norepinephrine synthesis and sympathovagal balance; variants may influence autonomic tone and susceptibility to orthostatic intolerance and POTS 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 DBH and the rs6271 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 DBH gene
The following variants in DBH are also studied in relation to chronic illness and may be analysed together for a more complete picture.
Frequently asked questions
What is the rs6271 variant in the DBH gene?
rs6271 is a single nucleotide polymorphism (SNP) located in the DBH (Dopamine Beta-Hydroxylase) gene, which is involved in norepinephrine biosynthesis. DBH encodes dopamine beta-hydroxylase, the enzyme that converts dopamine to norepinephrine in sympathetic neurons and adrenal chromaffin cells.
How may the rs6271 variant relate to Long COVID or ME/CFS?
DBH variants affect norepinephrine synthesis and sympathovagal balance; variants may influence autonomic tone and susceptibility to orthostatic intolerance and POTS in Long COVID.
Can a consumer DNA test detect the rs6271 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.
