What is the rs1799836 variant?
rs1799836 is a SNP (single nucleotide polymorphism) in the MAOB (Monoamine Oxidase B) gene. It belongs to the Neurotransmitter category and is part of the Methylation & Neurotransmitters biological cluster. MAOB encodes monoamine oxidase B, which preferentially catabolizes dopamine, benzylamine, and phenylethylamine.
Biological role and pathway
This variant sits within the MAOB gene, which is involved in the monoamine catabolism pathway. Genes within the Methylation & Neurotransmitters 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.
rs1799836 and Long COVID / ME-CFS research
MAOB variants may influence dopamine tone and contribute to motivation deficits, fatigue, and cognitive impairment 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 MAOB and the rs1799836 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 rs1799836 variant in the MAOB gene?
rs1799836 is a single nucleotide polymorphism (SNP) located in the MAOB (Monoamine Oxidase B) gene, which is involved in monoamine catabolism. MAOB encodes monoamine oxidase B, which preferentially catabolizes dopamine, benzylamine, and phenylethylamine.
How may the rs1799836 variant relate to Long COVID or ME/CFS?
MAOB variants may influence dopamine tone and contribute to motivation deficits, fatigue, and cognitive impairment in Long COVID.
Can a consumer DNA test detect the rs1799836 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.
