rs3219145
Variant in the PARP1 gene (Poly(ADP-Ribose) Polymerase 1)
rs3219145 is a single nucleotide polymorphism (SNP) in the PARP1 gene, involved in DNA damage response / NAD+ catabolism. Variants at this position have been studied in relation to immune function, metabolism, and chronic illness.

What is the rs3219145 variant?
rs3219145 is a SNP (single nucleotide polymorphism) in the PARP1 (Poly(ADP-Ribose) Polymerase 1) gene. It belongs to the Genome Stability category and is part of the Mitochondrial Energy Production & PEM biological cluster. PARP1 is a major NAD+ consumer that poly-ADP-ribosylates proteins at sites of DNA damage, consuming large amounts of NAD+.
Biological role and pathway
This variant sits within the PARP1 gene, which is involved in the DNA damage response / NAD+ catabolism pathway. Genes within the Mitochondrial Energy Production & PEM 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.
rs3219145 and Long COVID / ME-CFS research
Excessive PARP1 activation depletes NAD+ and impairs mitochondrial function; in viral infection and Long COVID, high PARP1 activity may contribute to NAD+ depletion and cellular energy failure.

Frequently asked questions
What is the rs3219145 variant in the PARP1 gene?
rs3219145 is a single nucleotide polymorphism (SNP) located in the PARP1 (Poly(ADP-Ribose) Polymerase 1) gene, which is involved in DNA damage response / NAD+ catabolism. PARP1 is a major NAD+ consumer that poly-ADP-ribosylates proteins at sites of DNA damage, consuming large amounts of NAD+.
How may the rs3219145 variant relate to Long COVID or ME/CFS?
Excessive PARP1 activation depletes NAD+ and impairs mitochondrial function; in viral infection and Long COVID, high PARP1 activity may contribute to NAD+ depletion and cellular energy failure.
Can a consumer DNA test detect the rs3219145 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.
