What is the rs28934889 variant?
rs28934889 is a SNP (single nucleotide polymorphism) in the MUT (Methylmalonyl-CoA Mutase) gene. It belongs to the Metabolic category and is part of the Methylation & Neurotransmitters biological cluster. MUT encodes methylmalonyl-CoA mutase, a B12-dependent enzyme that converts methylmalonyl-CoA to succinyl-CoA for entry into the TCA cycle.
Biological role and pathway
This variant sits within the MUT gene, which is involved in the B12-dependent organic acid metabolism 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.
rs28934889 and Long COVID / ME-CFS research
MUT requires adenosylcobalamin (B12); functional variants may affect B12 metabolism and organic acid accumulation, contributing to neurological symptoms in Long COVID.

Frequently asked questions
What is the rs28934889 variant in the MUT gene?
rs28934889 is a single nucleotide polymorphism (SNP) located in the MUT (Methylmalonyl-CoA Mutase) gene, which is involved in B12-dependent organic acid metabolism. MUT encodes methylmalonyl-CoA mutase, a B12-dependent enzyme that converts methylmalonyl-CoA to succinyl-CoA for entry into the TCA cycle.
How may the rs28934889 variant relate to Long COVID or ME/CFS?
MUT requires adenosylcobalamin (B12); functional variants may affect B12 metabolism and organic acid accumulation, contributing to neurological symptoms in Long COVID.
Can a consumer DNA test detect the rs28934889 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.
