What is the rs3219484 variant?

rs3219484 is a SNP (single nucleotide polymorphism) in the MUTYH (MutY DNA Glycosylase) gene. It belongs to the Dna Repair category and is part of the DNA Repair biological cluster. MUTYH encodes a DNA glycosylase that removes adenine misincorporated opposite 8-oxoguanine, working alongside OGG1 to prevent oxidative DNA damage.

Biological role and pathway

This variant sits within the MUTYH gene, which is involved in the base excision repair pathway. Genes within the DNA Repair 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.

rs3219484 and Long COVID / ME-CFS research

MUTYH variants reducing oxidative DNA damage repair may increase genomic instability under the elevated reactive oxygen species in Long COVID.

Frequently asked questions

What is the rs3219484 variant in the MUTYH gene?

rs3219484 is a single nucleotide polymorphism (SNP) located in the MUTYH (MutY DNA Glycosylase) gene, which is involved in base excision repair. MUTYH encodes a DNA glycosylase that removes adenine misincorporated opposite 8-oxoguanine, working alongside OGG1 to prevent oxidative DNA damage.

How may the rs3219484 variant relate to Long COVID or ME/CFS?

MUTYH variants reducing oxidative DNA damage repair may increase genomic instability under the elevated reactive oxygen species in Long COVID.

Can a consumer DNA test detect the rs3219484 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.
