PARP1 Gene

What is the PARP1 gene?

PARP1 encodes poly(adp-ribose) polymerase 1, a protein involved in DNA damage response. It belongs to the Dna Repair category and is part of the DNA Repair & Genomic Stability biological cluster. PARP1 detects DNA strand breaks and synthesizes poly(ADP-ribose) chains to recruit repair factors. It consumes large amounts of NAD+ during DNA damage responses and is a major regulator of cell death decisions.

Biological role and pathway

PARP1 is involved in the DNA damage response pathway, which plays a central role in regulating physiological processes relevant to immune defence, cellular energy, and systemic homeostasis. Genes within the DNA Repair & Genomic Stability 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 in these systems — particularly under conditions of physiological stress such as viral infection or prolonged illness.

Known genetic variants

The following variants (SNPs) in the PARP1 gene have been studied in relation to dna repair and chronic illness. Each variant represents a single nucleotide position where individuals may carry different alleles.

• rs1136410— PARP1 variant
• rs2230484— PARP1 variant
• rs3219090— PARP1 variant

Conditions studied in relation to PARP1

Research into PARP1 variants has explored associations with the following conditions. These are areas of scientific investigation and do not imply that PARP1 causes or treats any condition.

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 PARP1 and related genes in the dna repair & genomic stability pathway.

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.
